1 00:00:00,006 --> 00:00:03,060 well hello internet and welcome my learn 2 00:00:01,092 --> 00:00:05,106 to program tutorial in this tutorial 3 00:00:03,006 --> 00:00:07,041 series is going to be multi-part series 4 00:00:06,006 --> 00:00:10,023 I'm going to teach you how to program 5 00:00:07,095 --> 00:00:11,103 through problem-solving I'm basically 6 00:00:10,023 --> 00:00:14,025 going to show you how to do a couple 7 00:00:12,003 --> 00:00:15,057 different things using Python that's a 8 00:00:14,025 --> 00:00:17,040 language I'm going to use and then I'm 9 00:00:15,057 --> 00:00:18,072 going to ask you a question ask you to 10 00:00:17,004 --> 00:00:20,303 solve it and then I'm going to show you 11 00:00:18,072 --> 00:00:21,105 how I solved it a lot of people get 12 00:00:20,699 --> 00:00:24,210 confused about programming but 13 00:00:22,005 --> 00:00:26,100 programming basically involves listing 14 00:00:24,021 --> 00:00:29,022 all the things that must happen to solve 15 00:00:27,000 --> 00:00:31,005 a problem and whenever you're writing a 16 00:00:29,022 --> 00:00:33,611 program you have to first determine step 17 00:00:31,005 --> 00:00:35,064 by step what needs to happen and then 18 00:00:33,809 --> 00:00:37,980 you need to convert those steps in to 19 00:00:36,009 --> 00:00:40,011 the language being Python in this 20 00:00:37,098 --> 00:00:41,166 situation based off of many requests 21 00:00:40,029 --> 00:00:45,036 I've received I'm going to use PyCharm 22 00:00:42,066 --> 00:00:46,164 in this tutorial series and at the end 23 00:00:45,036 --> 00:00:48,114 of this tutorial series at the end of 24 00:00:47,064 --> 00:00:51,503 this video I show you how to install 25 00:00:49,014 --> 00:00:54,030 PyCharm and in the description 26 00:00:52,079 --> 00:00:56,430 underneath the video you can just click 27 00:00:54,003 --> 00:00:58,262 on that and jump directly to that part 28 00:00:56,043 --> 00:01:00,062 and watch how to install it if you'd 29 00:00:58,559 --> 00:01:02,564 like to use Python or you could use 30 00:01:00,449 --> 00:01:04,470 whatever different platform you'd like 31 00:01:02,609 --> 00:01:07,170 to use the program Python we're 32 00:01:04,047 --> 00:01:08,079 specifically going to use Python 3 in 33 00:01:07,017 --> 00:01:10,053 this situation and also in the 34 00:01:08,079 --> 00:01:11,147 description there is both a cheat sheet 35 00:01:10,053 --> 00:01:15,002 as well as a transcript of the entire 36 00:01:12,047 --> 00:01:17,079 tutorial and enough talking let's get 37 00:01:15,479 --> 00:01:19,532 into it now this whole tutorial series 38 00:01:17,079 --> 00:01:20,588 is going to be basically code writing it 39 00:01:20,009 --> 00:01:24,090 isn't going to be a whole bunch of 40 00:01:21,299 --> 00:01:25,650 frames that you just look at and read so 41 00:01:24,009 --> 00:01:27,027 this is basically going to be the only 42 00:01:25,065 --> 00:01:28,074 one we're going to look at and basically 43 00:01:27,027 --> 00:01:31,089 what we're going to talk about here is 44 00:01:28,074 --> 00:01:33,593 what every program language is going to 45 00:01:31,089 --> 00:01:35,154 allow you to do each language is going 46 00:01:34,259 --> 00:01:38,820 to have the ability to accept input and 47 00:01:36,054 --> 00:01:40,143 store it in many ways also the ability 48 00:01:38,082 --> 00:01:43,125 to output information to the screen or 49 00:01:41,043 --> 00:01:45,135 files or other different places also the 50 00:01:44,025 --> 00:01:48,027 ability to conditionally do one thing or 51 00:01:46,035 --> 00:01:50,070 another thing based off of different 52 00:01:48,045 --> 00:01:53,052 conditions they also allow you to do 53 00:01:50,007 --> 00:01:54,011 something multiple different times they 54 00:01:53,052 --> 00:01:57,057 also allow you to make mathematical 55 00:01:55,001 --> 00:02:00,036 calculations and they provide the 56 00:01:58,002 --> 00:02:02,201 ability to change data and if it's an 57 00:02:00,045 --> 00:02:04,004 object-oriented programming language 58 00:02:02,219 --> 00:02:07,710 like Python it's going to allow you to 59 00:02:04,409 --> 00:02:10,410 model real world objects using code and 60 00:02:07,071 --> 00:02:11,077 that is a short list but for the most 61 00:02:10,041 --> 00:02:13,950 part that covers what every program 62 00:02:12,031 --> 00:02:16,045 language is going to allow you to do so 63 00:02:14,319 --> 00:02:17,680 it's not that complicated and now we're 64 00:02:16,045 --> 00:02:19,081 going to jump over and we're going to 65 00:02:17,068 --> 00:02:21,109 start writing some code okay so to start 66 00:02:19,081 --> 00:02:22,980 a new project inside of pycharm you're 67 00:02:22,009 --> 00:02:25,045 just going to come down here and this is 68 00:02:23,709 --> 00:02:27,370 on Macintosh I'll show you Windows and 69 00:02:25,045 --> 00:02:28,134 second click on create new project and 70 00:02:27,037 --> 00:02:31,069 then we can go and save this wherever 71 00:02:29,034 --> 00:02:34,078 location untitled we're going to click 72 00:02:31,069 --> 00:02:37,105 on this and I'm going to find a location 73 00:02:34,078 --> 00:02:38,167 this is perfectly fine click on OK then 74 00:02:38,005 --> 00:02:41,080 you want to make sure that you pick the 75 00:02:39,067 --> 00:02:42,666 version three point five point one the 76 00:02:41,008 --> 00:02:44,089 new version of Python you installed 77 00:02:43,269 --> 00:02:47,313 click on that click on create it's going 78 00:02:45,061 --> 00:02:48,154 to say so I'd empty data might give you 79 00:02:47,709 --> 00:02:51,310 a different piece of information and 80 00:02:49,054 --> 00:02:53,083 then to create a new file you're going 81 00:02:51,031 --> 00:02:56,032 to go file and new and then you're going 82 00:02:53,083 --> 00:02:59,119 to go file and then we are going to call 83 00:02:56,041 --> 00:03:02,053 this Python Tut and the extension for 84 00:03:00,019 --> 00:03:04,093 Python files is dot py and click on 85 00:03:02,053 --> 00:03:06,055 people or click on ok and there you are 86 00:03:04,093 --> 00:03:07,096 for Mac and for Windows you're going to 87 00:03:06,073 --> 00:03:09,115 do pretty much exactly the same thing 88 00:03:08,023 --> 00:03:11,116 create a new project you're going to 89 00:03:10,015 --> 00:03:13,114 find a location that's perfectly fine 90 00:03:12,016 --> 00:03:15,103 we're going to say ok you're going to 91 00:03:14,014 --> 00:03:18,103 make sure that you have version 3.5 92 00:03:16,003 --> 00:03:20,712 point 1 of Python click on create it's 93 00:03:19,003 --> 00:03:22,992 going to say it's not empty click on yes 94 00:03:20,739 --> 00:03:26,500 and then come over here and click on 95 00:03:23,019 --> 00:03:28,450 file and new and new file and I'm going 96 00:03:26,005 --> 00:03:30,054 to call this Python Tut as well you can 97 00:03:28,045 --> 00:03:32,092 call whatever you want of course dot py 98 00:03:30,549 --> 00:03:36,040 click on OK and now you're ready to 99 00:03:32,092 --> 00:03:37,131 program alright so here we are inside of 100 00:03:36,004 --> 00:03:39,088 pycharm and once again in the 101 00:03:37,959 --> 00:03:41,410 description click on that it's going to 102 00:03:39,088 --> 00:03:41,185 jump you to the end of the video and it 103 00:03:41,041 --> 00:03:44,104 will show you how to install it on Mac 104 00:03:42,085 --> 00:03:45,154 or Windows either one of them so 105 00:03:45,004 --> 00:03:49,075 basically what we're going to do here is 106 00:03:46,054 --> 00:03:51,115 we are going to want to ask the user of 107 00:03:49,075 --> 00:03:53,784 our program to enter in their name and 108 00:03:52,015 --> 00:03:56,026 then we are going to say hello and 109 00:03:54,459 --> 00:03:58,750 follow that up with whatever their name 110 00:03:56,026 --> 00:04:00,315 is now remember I said previously that 111 00:03:58,075 --> 00:04:02,116 we need to list all the things we want 112 00:04:00,549 --> 00:04:05,470 to happen to solve our problem so what 113 00:04:03,016 --> 00:04:07,155 we want to do here is we want to first 114 00:04:05,047 --> 00:04:09,156 off if you put a hash symbol right there 115 00:04:07,299 --> 00:04:11,620 that's a comment that means the Python 116 00:04:09,579 --> 00:04:13,810 interpreter is going to just regard 117 00:04:11,062 --> 00:04:15,651 everything you put there and it is very 118 00:04:13,081 --> 00:04:17,850 good to comment your code if you want to 119 00:04:16,209 --> 00:04:20,830 have a multi-line comment just put those 120 00:04:18,579 --> 00:04:22,510 three little quotes like that and look 121 00:04:20,083 --> 00:04:22,172 at that now you have a multi-line 122 00:04:22,051 --> 00:04:25,100 comment 123 00:04:23,072 --> 00:04:27,098 okay pretty cool stuff so you can 124 00:04:26,000 --> 00:04:29,081 remember that for later pretty easy to 125 00:04:27,098 --> 00:04:31,169 remember but what we want to do here is 126 00:04:29,081 --> 00:04:33,137 we want to just start writing out 127 00:04:32,069 --> 00:04:37,100 exactly what we want to happen 128 00:04:34,037 --> 00:04:44,074 so we're going to say ask the user to 129 00:04:38,000 --> 00:04:49,001 input their name and assign it to a 130 00:04:44,074 --> 00:04:50,108 variable named name and we have to have 131 00:04:49,001 --> 00:04:53,087 a place to store things and variables 132 00:04:51,008 --> 00:04:55,082 allow us to say this is a name and it's 133 00:04:53,087 --> 00:04:57,182 going to be associated with a certain 134 00:04:55,082 --> 00:05:00,137 piece of data so how do we convert that 135 00:04:58,082 --> 00:05:03,095 into Python well we want to create a 136 00:05:01,037 --> 00:05:06,068 variable name name and there it is and 137 00:05:03,095 --> 00:05:08,114 then we want to accept input from the 138 00:05:06,068 --> 00:05:10,130 user so we just type in input we want to 139 00:05:09,014 --> 00:05:13,043 put a message on the screen so the user 140 00:05:11,003 --> 00:05:16,037 can see it and that message is going to 141 00:05:13,043 --> 00:05:17,129 be what is your name and you don't have 142 00:05:16,064 --> 00:05:20,069 to put anything else there and you can 143 00:05:18,029 --> 00:05:22,046 skip down to the next line so what do we 144 00:05:20,069 --> 00:05:26,074 want to do now that we have that all set 145 00:05:22,046 --> 00:05:32,005 up well we simply want to print out 146 00:05:26,074 --> 00:05:33,107 hello followed by the name they entered 147 00:05:32,419 --> 00:05:35,990 okay that's it it's pretty simple 148 00:05:34,007 --> 00:05:37,103 program and how do we print things out 149 00:05:35,099 --> 00:05:38,174 on the screen well we just call for 150 00:05:38,003 --> 00:05:42,008 print because we want to print out on 151 00:05:39,074 --> 00:05:42,140 the screen and then we type in exactly 152 00:05:42,008 --> 00:05:45,026 what we want to have here so we're going 153 00:05:43,004 --> 00:05:47,023 to have hello and we're going to 154 00:05:45,026 --> 00:05:48,107 separate all of the different things 155 00:05:47,419 --> 00:05:51,410 we're going to print out to the screen 156 00:05:49,007 --> 00:05:53,060 so here is going to be a string which is 157 00:05:51,041 --> 00:05:55,300 just a bunch of characters and here 158 00:05:53,006 --> 00:05:58,052 we're going to say that we want the data 159 00:05:55,669 --> 00:06:00,260 that is stored inside of name to also be 160 00:05:59,006 --> 00:06:02,102 printed out on the screen 161 00:06:00,026 --> 00:06:04,028 now I'm going to run this and you can 162 00:06:03,002 --> 00:06:07,007 see right here at the bottom of the 163 00:06:04,028 --> 00:06:09,101 screen it says what is your name and I 164 00:06:07,007 --> 00:06:11,102 am going to type in my name look at this 165 00:06:10,001 --> 00:06:14,033 I made a mistake already I'm supposed to 166 00:06:12,002 --> 00:06:17,045 be an expert let's go and put a space 167 00:06:14,033 --> 00:06:19,094 inside of there and let's rerun this so 168 00:06:17,045 --> 00:06:21,107 rerun it what is your name and I'm going 169 00:06:19,094 --> 00:06:23,129 to type in Derrick and hit enter and 170 00:06:22,007 --> 00:06:26,072 it's going to say hello Derrick just 171 00:06:24,029 --> 00:06:27,086 like that so pretty simple little 172 00:06:26,072 --> 00:06:28,801 program 173 00:06:27,086 --> 00:06:30,152 and we're going to get much more 174 00:06:29,449 --> 00:06:33,830 complicated as these go on and of course 175 00:06:31,052 --> 00:06:35,096 I'm going to start asking you questions 176 00:06:33,083 --> 00:06:37,121 and then I'm going to pause the video 177 00:06:35,096 --> 00:06:40,100 you're going to write the code and then 178 00:06:38,021 --> 00:06:42,790 you are going to then be able to just 179 00:06:41,000 --> 00:06:45,053 learn through problem solving so another 180 00:06:42,979 --> 00:06:47,053 thing just before we move on is variable 181 00:06:45,053 --> 00:06:50,084 names can either start with a letter any 182 00:06:47,719 --> 00:06:53,270 letter you'd like or underscores and you 183 00:06:50,084 --> 00:06:55,153 can of course come in here and separate 184 00:06:53,027 --> 00:06:58,121 these you can say something like the 185 00:06:55,909 --> 00:07:02,180 name like that and after the first 186 00:06:59,021 --> 00:07:05,087 letter inside of here you can also come 187 00:07:02,018 --> 00:07:07,657 in and also use numbers so that is the 188 00:07:05,087 --> 00:07:09,196 ways that you would create variable 189 00:07:07,819 --> 00:07:10,894 names which are just storage cells and 190 00:07:09,979 --> 00:07:14,032 it's also very important that those 191 00:07:11,569 --> 00:07:17,710 variable names are not any of these 192 00:07:14,509 --> 00:07:20,593 words right here so you can't use and 193 00:07:17,071 --> 00:07:22,150 DDL from da-da-da-da-da not anything you 194 00:07:21,349 --> 00:07:25,381 really need to worry about and as you 195 00:07:22,789 --> 00:07:27,826 learn more about Python you are going to 196 00:07:25,669 --> 00:07:30,560 just know that these are commands used 197 00:07:28,159 --> 00:07:32,194 in Python and you cannot use them who's 198 00:07:30,056 --> 00:07:33,155 going to name anything lambda anyway or 199 00:07:32,509 --> 00:07:36,830 a variable named 4 these are all pretty 200 00:07:34,055 --> 00:07:39,071 weird things and by no means should you 201 00:07:36,083 --> 00:07:40,702 go in and try to memorize that ok so now 202 00:07:39,071 --> 00:07:42,077 let's do something a little bit more 203 00:07:41,449 --> 00:07:47,360 complicated basically what we're going 204 00:07:43,031 --> 00:07:49,510 to do is allow your users to do math on 205 00:07:47,036 --> 00:07:51,038 to values that they enter so what are we 206 00:07:49,789 --> 00:07:52,870 going to do we're going to type out 207 00:07:51,056 --> 00:07:56,125 exactly what needs to be done so we're 208 00:07:53,599 --> 00:07:58,678 going to say ask the user and you should 209 00:07:56,629 --> 00:08:01,610 do this for every program I even do it 210 00:07:59,389 --> 00:08:02,467 today with very very big programs so 211 00:08:01,061 --> 00:08:09,340 we're going to say ask the user to input 212 00:08:03,169 --> 00:08:12,178 two values and store them in variables 213 00:08:09,889 --> 00:08:15,898 that are going to have the name of num1 214 00:08:12,259 --> 00:08:17,360 and num2 what we're going to then do 215 00:08:15,979 --> 00:08:19,075 that's going to be a little bit 216 00:08:17,036 --> 00:08:21,065 different is whenever these pieces of 217 00:08:19,939 --> 00:08:23,941 data come in they are all considered 218 00:08:21,065 --> 00:08:26,074 just random bits of characters or 219 00:08:24,139 --> 00:08:29,214 strings so what we're going to have to 220 00:08:26,659 --> 00:08:34,390 do is figure out a way to convert the 221 00:08:29,889 --> 00:08:36,710 strings that the users enter in into 222 00:08:34,039 --> 00:08:38,087 regular number 223 00:08:36,071 --> 00:08:40,390 and these regular numbers are not going 224 00:08:38,087 --> 00:08:42,316 to have decimal places and in situations 225 00:08:41,029 --> 00:08:45,290 in which you have a variable that 226 00:08:43,099 --> 00:08:49,123 doesn't have a decimal place it is known 227 00:08:45,029 --> 00:08:51,268 as an integer okay so we received the 228 00:08:49,339 --> 00:08:54,200 pieces of data that we want the two 229 00:08:51,529 --> 00:08:55,585 numbers that we want to sum together so 230 00:08:54,002 --> 00:09:01,951 what do we need to do that we need to 231 00:08:56,089 --> 00:09:05,630 add the values entered and store in a 232 00:09:02,149 --> 00:09:07,910 variable named sum okay pretty simple 233 00:09:05,063 --> 00:09:09,095 stuff and then what do we need to do 234 00:09:07,091 --> 00:09:12,091 well let's go and do a little bit more 235 00:09:09,095 --> 00:09:18,104 math let's also say that we want to 236 00:09:12,091 --> 00:09:21,092 subtract values and store in a variable 237 00:09:19,004 --> 00:09:25,013 that is known as difference and let's do 238 00:09:22,001 --> 00:09:31,004 some more we will multiply the values 239 00:09:25,094 --> 00:09:34,105 and store in a variable that is named 240 00:09:31,004 --> 00:09:39,062 product and finally we will divide the 241 00:09:35,005 --> 00:09:41,012 values and store in another variable 242 00:09:39,062 --> 00:09:42,158 that is going to be called quotients and 243 00:09:41,075 --> 00:09:46,124 what the heck let's do another one and 244 00:09:43,058 --> 00:09:50,086 then we also want to use a funky little 245 00:09:47,024 --> 00:09:55,076 tool that we have called modulus on the 246 00:09:50,086 --> 00:09:57,122 values to find the remainder and guess 247 00:09:55,076 --> 00:09:59,138 what we are going to call that remainder 248 00:09:58,022 --> 00:10:04,079 and let's do another one we're going to 249 00:10:00,038 --> 00:10:06,041 print the results on the screen for the 250 00:10:04,079 --> 00:10:08,093 user because it wouldn't be useful if it 251 00:10:06,068 --> 00:10:10,142 didn't do that and I guess that's 252 00:10:08,093 --> 00:10:12,442 basically it so now after we created all 253 00:10:11,042 --> 00:10:14,581 the steps that we need to do we're going 254 00:10:13,279 --> 00:10:17,750 to come in here and fill it in with 255 00:10:14,959 --> 00:10:20,510 Python code so how do we receive two 256 00:10:17,075 --> 00:10:22,654 pieces of data inside of Python pretty 257 00:10:20,051 --> 00:10:25,055 simple we used input before so of course 258 00:10:23,329 --> 00:10:30,230 we're going to have input is going to be 259 00:10:25,091 --> 00:10:31,175 used and we're going to again type in 260 00:10:30,023 --> 00:10:36,057 the men the message we want so we're 261 00:10:32,075 --> 00:10:38,163 going to say enter two numbers and then 262 00:10:36,057 --> 00:10:41,103 we are going to receive two numbers and 263 00:10:39,063 --> 00:10:43,116 there's a fancy little function inside 264 00:10:42,003 --> 00:10:46,005 of function inside of Python called 265 00:10:44,016 --> 00:10:47,115 split what it's going to do is it's 266 00:10:46,023 --> 00:10:49,059 going to you're going to enter not two 267 00:10:48,015 --> 00:10:52,026 numbers let's say they're two and four 268 00:10:49,059 --> 00:10:53,100 well we have to decide how are we going 269 00:10:52,026 --> 00:10:56,079 to take these two numbers that they 270 00:10:54,000 --> 00:10:59,019 enter in well what split does is it says 271 00:10:56,079 --> 00:11:00,123 if there is a space or whitespace 272 00:10:59,019 --> 00:11:03,057 between these numbers we are going to 273 00:11:01,023 --> 00:11:06,081 separate those values that way and then 274 00:11:03,057 --> 00:11:08,109 we're going to have to assign them to 275 00:11:06,081 --> 00:11:10,116 variables and if you want to have two 276 00:11:09,009 --> 00:11:13,017 variables one is called num1 and the 277 00:11:11,016 --> 00:11:14,070 other one's called num2 you just put the 278 00:11:13,017 --> 00:11:16,023 two of them in there just like you did 279 00:11:14,007 --> 00:11:17,043 with the one previously and there you go 280 00:11:16,077 --> 00:11:19,173 now you're going to be able to receive 281 00:11:18,006 --> 00:11:22,101 two pieces of data instead of just one 282 00:11:20,073 --> 00:11:25,077 so pretty cool stuff we then have to 283 00:11:23,001 --> 00:11:28,017 convert our strings so that python knows 284 00:11:26,013 --> 00:11:29,094 that we're working with integers and 285 00:11:28,017 --> 00:11:32,025 that's pretty easy to do we just say 286 00:11:29,094 --> 00:11:33,156 that we want to store inside of the 287 00:11:32,025 --> 00:11:37,119 number one variable an integer version 288 00:11:34,056 --> 00:11:39,141 of num1 and then we can go and do 289 00:11:38,019 --> 00:11:43,050 exactly the same thing for num2 290 00:11:40,041 --> 00:11:45,138 so there's num2 and there's num2 so it's 291 00:11:43,005 --> 00:11:48,057 just converting a string into an integer 292 00:11:46,038 --> 00:11:51,042 it's all it's doing now we need to add 293 00:11:49,002 --> 00:11:52,071 these values and store them into a 294 00:11:51,042 --> 00:11:55,080 variable called sum 295 00:11:52,071 --> 00:11:57,153 pretty easy to do we just say num1 plus 296 00:11:55,008 --> 00:11:59,013 num2 pretty much exactly the way that 297 00:11:58,053 --> 00:12:00,135 you would think it would work 298 00:11:59,085 --> 00:12:02,157 so we're going to take the value in here 299 00:12:01,035 --> 00:12:05,103 add it to the value in here and store it 300 00:12:03,057 --> 00:12:07,092 inside of this guy right here let's go 301 00:12:06,003 --> 00:12:09,087 and do the same thing with subtraction 302 00:12:07,092 --> 00:12:10,185 and all we do is change that guy right 303 00:12:09,087 --> 00:12:12,186 there when we want to multiply we're 304 00:12:11,085 --> 00:12:14,181 just going to go and put a star inside 305 00:12:13,086 --> 00:12:16,179 of there like that if we want to divide 306 00:12:15,081 --> 00:12:19,127 we're going to change this to divide and 307 00:12:17,079 --> 00:12:21,123 be modulus which is going to give us the 308 00:12:20,027 --> 00:12:23,091 remainder we're just going to come in 309 00:12:22,023 --> 00:12:26,115 here and we're going to put it like that 310 00:12:23,091 --> 00:12:28,098 but this is sum we can't use these 311 00:12:27,015 --> 00:12:31,071 variables these variable names because 312 00:12:29,061 --> 00:12:33,087 it would overwrite the value stored in 313 00:12:31,071 --> 00:12:35,094 some each time and we already know that 314 00:12:33,087 --> 00:12:37,094 we want to store those in variables 315 00:12:35,094 --> 00:12:40,119 called difference in this situation and 316 00:12:38,057 --> 00:12:43,098 product in the situation because we 317 00:12:41,019 --> 00:12:46,026 wrote all this stuff out and quotient in 318 00:12:43,098 --> 00:12:47,207 this situation right here and then 319 00:12:46,026 --> 00:12:49,955 finally remainder 320 00:12:48,089 --> 00:12:52,100 like we have right here but now we want 321 00:12:50,189 --> 00:12:53,270 to print our results and we want to 322 00:12:52,199 --> 00:12:57,260 print them in a format let's say that 323 00:12:53,999 --> 00:13:00,062 they enter 5 + + 4 inside of here what 324 00:12:57,809 --> 00:13:04,814 we want to do is we want to go and print 325 00:13:00,629 --> 00:13:07,800 it out on the screen 5 + 4 is equal to 9 326 00:13:05,309 --> 00:13:09,356 so how are we going to do that with our 327 00:13:07,008 --> 00:13:11,025 print statement we can't do it in its 328 00:13:09,779 --> 00:13:15,660 current format so what we're going to do 329 00:13:11,097 --> 00:13:16,185 instead is we need to format our output 330 00:13:15,066 --> 00:13:18,995 onto the screen whenever it's printed 331 00:13:17,085 --> 00:13:20,160 we're going to still use print just like 332 00:13:19,589 --> 00:13:24,120 we did before and what we're going to do 333 00:13:21,006 --> 00:13:26,975 at the end of this is like I said we 334 00:13:24,012 --> 00:13:31,451 need to format our output and we need to 335 00:13:27,569 --> 00:13:33,650 say num1 and num2 and then some 336 00:13:31,559 --> 00:13:35,591 but how inside of this little string 337 00:13:34,379 --> 00:13:37,412 inside of here remember if it's in 338 00:13:35,879 --> 00:13:38,966 quotes it's a string we're just building 339 00:13:37,709 --> 00:13:42,660 it ourselves how are we going to say 340 00:13:39,749 --> 00:13:43,787 we're num1 num2 and some go to well we 341 00:13:42,066 --> 00:13:45,129 just come in here and throw in some 342 00:13:44,129 --> 00:13:48,540 curly brackets and throw in some more 343 00:13:46,029 --> 00:13:50,037 curly brackets and then throw in one 344 00:13:48,054 --> 00:13:51,135 more curly bracket and what this is 345 00:13:50,037 --> 00:13:54,042 going to do for us is it's going to take 346 00:13:52,035 --> 00:13:56,834 this number one right over the value 4 347 00:13:54,042 --> 00:13:58,098 it is and throw it right there num2 is 348 00:13:57,149 --> 00:14:01,290 going to be thrown in right there and 349 00:13:58,098 --> 00:14:02,142 then some is going to be thrown in right 350 00:14:01,029 --> 00:14:05,798 there so that is how we can format all 351 00:14:03,042 --> 00:14:08,951 of our data we can just come in here and 352 00:14:06,059 --> 00:14:11,123 do this a couple times and then we will 353 00:14:09,329 --> 00:14:13,331 just change that to subtraction we can 354 00:14:11,699 --> 00:14:16,050 come up here make sure that we have our 355 00:14:13,529 --> 00:14:18,240 variable names exactly the same and also 356 00:14:16,005 --> 00:14:21,054 if I didn't mention this previously 357 00:14:18,024 --> 00:14:23,783 difference is completely different from 358 00:14:21,054 --> 00:14:26,085 difference it's this case sensitive so 359 00:14:23,999 --> 00:14:29,160 make sure you use exactly the same 360 00:14:26,085 --> 00:14:30,090 variable name and also we can come up 361 00:14:29,016 --> 00:14:34,115 here and get product bring this down 362 00:14:31,035 --> 00:14:36,129 here change this to multiply and throw 363 00:14:34,259 --> 00:14:38,321 in products right there and quotient 364 00:14:37,029 --> 00:14:40,988 whenever your very first starting off 365 00:14:38,879 --> 00:14:42,990 with programming it is a good idea to 366 00:14:41,249 --> 00:14:44,288 just come in here copy and paste make 367 00:14:42,099 --> 00:14:45,248 sure these variable names are exactly 368 00:14:44,639 --> 00:14:49,658 the same that's not a problem 369 00:14:46,139 --> 00:14:52,180 and then remainder for the modulus and 370 00:14:49,829 --> 00:14:55,210 let's change to this and 371 00:14:52,018 --> 00:14:57,061 remainder and if we save that and then 372 00:14:55,021 --> 00:14:59,023 we run it we come down here enter two 373 00:14:57,061 --> 00:15:01,072 numbers and the two numbers we're going 374 00:14:59,041 --> 00:15:04,054 to enter our five remember the space and 375 00:15:01,072 --> 00:15:06,100 a four hit enter and is going to go and 376 00:15:04,054 --> 00:15:08,098 output our data exactly the way that we 377 00:15:07,000 --> 00:15:10,036 think that it should and let's just move 378 00:15:08,098 --> 00:15:12,103 this up here so you can see everything 379 00:15:10,036 --> 00:15:14,110 all at once so there you go that is how 380 00:15:13,003 --> 00:15:16,012 we go about receiving all that 381 00:15:15,001 --> 00:15:19,095 information and then providing the 382 00:15:16,093 --> 00:15:21,127 proper output and now based off of 383 00:15:20,004 --> 00:15:25,006 everything you learned right there I 384 00:15:22,027 --> 00:15:27,031 think you are ready to solve your first 385 00:15:25,024 --> 00:15:30,076 Python program so what we want to do 386 00:15:27,067 --> 00:15:32,155 here is our problem let's go and throw 387 00:15:30,076 --> 00:15:36,130 in a comment our problem is going to 388 00:15:33,055 --> 00:15:41,089 allow the user to enter miles 389 00:15:37,003 --> 00:15:46,021 so we'll say receive miles and convert 390 00:15:41,089 --> 00:15:48,187 to kilometers and then some information 391 00:15:46,048 --> 00:15:54,052 that we need to know is that kilometres 392 00:15:49,087 --> 00:15:57,115 is going to be equal to miles times one 393 00:15:54,088 --> 00:15:59,173 point six oh nine three four and the 394 00:15:58,015 --> 00:16:02,098 output are basically the program the way 395 00:16:00,073 --> 00:16:04,114 we want it to look here is the message 396 00:16:02,098 --> 00:16:07,102 is going to be printed out on screen is 397 00:16:05,014 --> 00:16:10,081 enter miles they are then going to be 398 00:16:08,002 --> 00:16:12,079 able to enter the number five and then 399 00:16:10,081 --> 00:16:16,144 we are going to output on the screen 400 00:16:12,079 --> 00:16:18,175 five miles equals and something like 8.0 401 00:16:17,044 --> 00:16:22,093 for something kilometers whatever that 402 00:16:19,075 --> 00:16:23,173 is so there you go so like it's a cheat 403 00:16:22,093 --> 00:16:25,147 sheet description you can refer to that 404 00:16:24,073 --> 00:16:27,073 so that you don't have to jump back and 405 00:16:26,047 --> 00:16:28,138 forth through the video or you could 406 00:16:27,073 --> 00:16:30,124 rewind the video or whatever you want to 407 00:16:29,038 --> 00:16:33,091 do but basically what I want you to be 408 00:16:31,024 --> 00:16:35,095 able to do here is to print out this 409 00:16:33,091 --> 00:16:37,147 string allow them to enter a number and 410 00:16:35,095 --> 00:16:40,108 then output this information and what 411 00:16:38,047 --> 00:16:42,115 you do right now is pause your screen go 412 00:16:41,008 --> 00:16:45,073 write the code and then come back and 413 00:16:43,015 --> 00:16:48,058 I'll show you the results or my solution 414 00:16:45,073 --> 00:16:50,080 for this program alright so here we are 415 00:16:48,058 --> 00:16:52,060 back again and now I'm going to walk 416 00:16:50,008 --> 00:16:53,101 step-by-step through exactly how to 417 00:16:52,006 --> 00:16:59,053 solve this so I'm going to say something 418 00:16:54,073 --> 00:17:01,114 like ask the user to input miles 419 00:17:00,007 --> 00:17:08,056 hopefully you went and typed all this 420 00:17:02,014 --> 00:17:10,039 out and assign it to the miles variable 421 00:17:08,056 --> 00:17:12,130 and what else are we going to need to do 422 00:17:10,039 --> 00:17:17,068 here well remember we need to convert 423 00:17:13,003 --> 00:17:19,078 from string to integer and yes there's 424 00:17:17,068 --> 00:17:23,082 other ways to do that I'll get into that 425 00:17:20,005 --> 00:17:28,081 later on we then also want to perform 426 00:17:23,082 --> 00:17:31,165 calculation by multiplying one point six 427 00:17:28,081 --> 00:17:34,117 zero nine three four times miles and 428 00:17:32,065 --> 00:17:37,134 save that in a variable called 429 00:17:35,017 --> 00:17:42,076 kilometers and then we want to print 430 00:17:38,034 --> 00:17:43,132 results using format yes I use kind of 431 00:17:42,076 --> 00:17:45,094 bad english whenever i'm typing out 432 00:17:44,032 --> 00:17:46,114 comments sometimes sorry about that 433 00:17:45,094 --> 00:17:47,191 hopefully it doesn't bother you all 434 00:17:47,014 --> 00:17:51,028 right so what we going to do right here 435 00:17:48,091 --> 00:17:53,113 well we're going to create a variable 436 00:17:51,028 --> 00:17:56,116 called miles and we want to receive 437 00:17:54,013 --> 00:18:01,027 input and we want to print out a message 438 00:17:57,016 --> 00:18:02,110 here that says enter miles and we'll 439 00:18:01,027 --> 00:18:06,079 throw a little space inside of there 440 00:18:03,001 --> 00:18:10,015 then we want to convert miles into an 441 00:18:06,079 --> 00:18:12,157 integer version of the variable called 442 00:18:10,024 --> 00:18:15,106 miles we need and then need to perform 443 00:18:13,057 --> 00:18:19,093 our calculations this is going to be 444 00:18:16,006 --> 00:18:23,050 kilometers is equal to miles times one 445 00:18:19,093 --> 00:18:24,184 point six oh nine three four and then we 446 00:18:23,005 --> 00:18:27,016 need to print our results using format 447 00:18:25,084 --> 00:18:28,159 and I showed you what I wanted you to 448 00:18:27,061 --> 00:18:30,142 print out before and we're going to 449 00:18:29,059 --> 00:18:33,142 throw in our curly brackets right there 450 00:18:31,042 --> 00:18:36,046 and we're going to say miles equals and 451 00:18:34,042 --> 00:18:38,113 then throw in with the kilometers come 452 00:18:36,082 --> 00:18:40,129 outside of that double quote and then 453 00:18:39,013 --> 00:18:42,100 we're going to say format and then what 454 00:18:41,029 --> 00:18:44,035 we want to go inside of there is going 455 00:18:43,000 --> 00:18:48,013 to be whatever is stored in the variable 456 00:18:44,089 --> 00:18:50,101 called miles and whatever is stored in 457 00:18:48,013 --> 00:18:52,102 the variable called kilometers we're 458 00:18:51,001 --> 00:18:55,006 going to save that and then we're going 459 00:18:53,002 --> 00:18:57,010 to run it and it's going to say enter 460 00:18:55,006 --> 00:19:00,037 miles in our example I typed in five and 461 00:18:57,082 --> 00:19:02,125 here we can see five miles equals eight 462 00:19:00,037 --> 00:19:04,132 point zero four six seven kilometers so 463 00:19:03,025 --> 00:19:07,124 there you go hopefully you did good with 464 00:19:05,032 --> 00:19:09,098 your first example if you didn't 465 00:19:08,024 --> 00:19:12,047 is not a problem at all you're going to 466 00:19:09,098 --> 00:19:14,120 have a lot of chances to do all of this 467 00:19:12,047 --> 00:19:17,051 right and like it said making mistakes 468 00:19:15,002 --> 00:19:19,061 is the best way to be able to learn how 469 00:19:17,051 --> 00:19:20,102 to program that's all programming is so 470 00:19:19,079 --> 00:19:22,115 now let's do something a little bit more 471 00:19:21,002 --> 00:19:25,010 interesting let's say we want to create 472 00:19:23,015 --> 00:19:27,032 a calculator so we want to be able to 473 00:19:25,001 --> 00:19:29,060 receive two numbers separated by the 474 00:19:27,032 --> 00:19:32,123 operator of choice and then we want to 475 00:19:29,069 --> 00:19:35,156 show a result so for example I want to 476 00:19:33,023 --> 00:19:38,066 output on the screen enter calculation 477 00:19:36,056 --> 00:19:40,115 and then I want them to be able to enter 478 00:19:38,066 --> 00:19:42,092 something like five times six and then 479 00:19:41,015 --> 00:19:45,053 it's going to output the proper 480 00:19:42,092 --> 00:19:46,148 information thereafter I then and we're 481 00:19:45,053 --> 00:19:51,053 going to print out on the screen five 482 00:19:47,048 --> 00:19:52,121 times six is equal to 30 okay but we are 483 00:19:51,053 --> 00:19:54,115 going to allow them to use addition 484 00:19:53,021 --> 00:19:57,098 subtraction multiplication or division 485 00:19:55,015 --> 00:20:00,044 whenever they are providing that 486 00:19:57,098 --> 00:20:01,154 information to us so here we are let's 487 00:20:00,044 --> 00:20:03,110 comment that out so it doesn't mess 488 00:20:02,054 --> 00:20:06,071 anything up and then we'll walk through 489 00:20:04,001 --> 00:20:12,067 exactly what we need to do here so we 490 00:20:06,071 --> 00:20:17,123 want to store the user input of two 491 00:20:12,076 --> 00:20:19,154 numbers and the operator of choice and 492 00:20:18,023 --> 00:20:26,060 then what do we want to do well we need 493 00:20:20,054 --> 00:20:28,097 to convert the strings into integers 494 00:20:26,006 --> 00:20:30,011 just the numbers though we're not going 495 00:20:28,097 --> 00:20:31,112 to convert the operator that they're 496 00:20:30,065 --> 00:20:33,119 going to be using then we're going to 497 00:20:32,012 --> 00:20:36,014 use a fancy tool remember I said before 498 00:20:34,019 --> 00:20:38,066 every programming language is going to 499 00:20:36,014 --> 00:20:41,057 provide the ability to perform different 500 00:20:38,066 --> 00:20:43,118 operations depending upon conditions so 501 00:20:41,057 --> 00:20:49,057 what we need to do here is we need to 502 00:20:44,018 --> 00:20:54,023 say if they enter plus then we need to 503 00:20:49,057 --> 00:20:55,136 provide output based on addition and 504 00:20:54,023 --> 00:20:57,104 then we're going to also do exactly the 505 00:20:56,036 --> 00:20:59,120 same thing with subtraction 506 00:20:58,004 --> 00:21:01,085 multiplication and division we'll just 507 00:21:00,002 --> 00:21:04,043 keep that there because we're smart we 508 00:21:01,085 --> 00:21:06,107 don't need to type out all that so then 509 00:21:04,061 --> 00:21:08,102 after we have that basically depending 510 00:21:07,007 --> 00:21:10,055 upon whatever the condition is we are 511 00:21:09,002 --> 00:21:14,057 then going to come in here 512 00:21:10,055 --> 00:21:15,062 and we are going to print the results 513 00:21:14,057 --> 00:21:17,084 and then our program is going to end 514 00:21:16,025 --> 00:21:18,074 because we don't really need to do 515 00:21:17,084 --> 00:21:21,086 anything else 516 00:21:18,074 --> 00:21:24,095 alright so store the user input of two 517 00:21:21,086 --> 00:21:26,132 numbers and the operator also feel free 518 00:21:24,095 --> 00:21:28,187 to pause the video anytime you would 519 00:21:27,032 --> 00:21:31,070 like to if you want to go and see if you 520 00:21:29,087 --> 00:21:32,141 can do it the right way so what I'm 521 00:21:31,007 --> 00:21:35,072 going to say is number one and an 522 00:21:33,041 --> 00:21:38,129 operator and number two and I want to 523 00:21:36,035 --> 00:21:43,070 receive the input for this and I'm going 524 00:21:39,029 --> 00:21:46,070 to type out enter calculation and then I 525 00:21:43,007 --> 00:21:48,071 will need to split those guys based off 526 00:21:46,007 --> 00:21:53,015 of whitespace and then need to convert 527 00:21:49,034 --> 00:21:56,108 number one into an integer and to do so 528 00:21:53,078 --> 00:21:58,121 we go and call our int function then 529 00:21:57,008 --> 00:22:01,103 we're going to do exactly the same thing 530 00:21:59,021 --> 00:22:03,029 for number two and there's number two 531 00:22:02,003 --> 00:22:06,014 and there's number two again we're not 532 00:22:04,001 --> 00:22:08,003 doing it for rid of the operator well 533 00:22:06,014 --> 00:22:10,085 then that brings us to if and how to 534 00:22:08,021 --> 00:22:14,033 perform different operations based off 535 00:22:10,085 --> 00:22:16,148 of conditions so how we use if is pretty 536 00:22:14,033 --> 00:22:21,041 easy we just type in if the operator 537 00:22:17,048 --> 00:22:22,142 they entered in is equal to and remember 538 00:22:21,041 --> 00:22:24,074 it wasn't converted in anything so it's 539 00:22:23,042 --> 00:22:26,123 still string so we have to put it 540 00:22:24,074 --> 00:22:29,120 between quotes we're going to say if the 541 00:22:27,023 --> 00:22:33,047 value for operator is equal to the plus 542 00:22:30,002 --> 00:22:35,096 sign well then put in our little colon 543 00:22:33,047 --> 00:22:37,136 and then we need to put some white space 544 00:22:36,014 --> 00:22:40,046 inside of here that's the way Python 545 00:22:38,036 --> 00:22:41,045 works that that's the way the Python 546 00:22:40,046 --> 00:22:43,055 knows that everything underneath here 547 00:22:42,026 --> 00:22:46,049 that's indented belongs to this 548 00:22:44,036 --> 00:22:48,068 condition if this condition comes true 549 00:22:46,049 --> 00:22:49,130 this is what's going to be executed and 550 00:22:48,068 --> 00:22:52,112 what specifically is going to be 551 00:22:50,003 --> 00:22:54,071 executed is our formatted data so we're 552 00:22:53,012 --> 00:22:56,087 going to go and put our little curly 553 00:22:54,098 --> 00:22:58,106 brackets inside of there again more 554 00:22:56,087 --> 00:22:59,096 curly brackets and then we're going to 555 00:22:59,006 --> 00:23:03,038 have another curly bracket and then 556 00:23:00,077 --> 00:23:04,112 we're going to say format and then this 557 00:23:03,038 --> 00:23:08,042 is going to be kind of neat we can go 558 00:23:05,012 --> 00:23:09,080 numb one inside of there and numb to 559 00:23:08,042 --> 00:23:11,045 inside of there but you're probably 560 00:23:09,008 --> 00:23:12,011 saying why didn't you do the calculation 561 00:23:11,072 --> 00:23:15,131 for this some or you can do the 562 00:23:13,001 --> 00:23:17,090 calculation directly inside of here so 563 00:23:16,031 --> 00:23:19,040 that's pretty cool stuff and that's all 564 00:23:17,099 --> 00:23:19,106 we want to do because we know the 565 00:23:19,004 --> 00:23:22,007 operator we know the number 566 00:23:20,069 --> 00:23:24,110 we don't want to do anything else so we 567 00:23:22,007 --> 00:23:27,098 want to jump out of that condition and 568 00:23:25,001 --> 00:23:30,065 basically exit the program unless the 569 00:23:28,061 --> 00:23:34,067 value for operator is not equal to plus 570 00:23:30,074 --> 00:23:36,152 in that situation we say else if but the 571 00:23:34,067 --> 00:23:39,098 people that designed Python were really 572 00:23:37,052 --> 00:23:42,119 cool funny people and they decided to 573 00:23:39,098 --> 00:23:44,135 just abbreviate that to LF exactly like 574 00:23:43,019 --> 00:23:48,032 that so now we're going to say operator 575 00:23:45,035 --> 00:23:50,072 is equal to and here we're going to say 576 00:23:48,032 --> 00:23:52,094 - and we're going to put our little 577 00:23:50,072 --> 00:23:54,095 colon inside of there again and in this 578 00:23:52,094 --> 00:23:56,138 situation we're just going to do a 579 00:23:54,095 --> 00:23:58,118 subtraction we want to tab in there 580 00:23:57,038 --> 00:24:00,104 print this right here throw in our 581 00:23:59,018 --> 00:24:02,117 subtraction right there throw in our 582 00:24:01,004 --> 00:24:05,021 subtraction right here and there we're 583 00:24:03,017 --> 00:24:07,064 ready to go and now we need to check the 584 00:24:05,021 --> 00:24:09,089 rest so we'll do an else if the other 585 00:24:07,064 --> 00:24:11,069 two conditions were not true what are we 586 00:24:09,089 --> 00:24:12,107 going to do throw that inside of there 587 00:24:11,069 --> 00:24:14,072 we're going to check if this was 588 00:24:13,007 --> 00:24:16,055 multiplication we're going to change 589 00:24:14,072 --> 00:24:17,075 that to multiplication and then we're 590 00:24:16,055 --> 00:24:19,142 going to change that to multiplication 591 00:24:17,075 --> 00:24:21,149 and then we have another one and in this 592 00:24:20,042 --> 00:24:23,129 situation that's going to be subtraction 593 00:24:22,049 --> 00:24:25,082 or that's going to be division sorry 594 00:24:24,029 --> 00:24:27,077 about that and we're going to throw in 595 00:24:25,082 --> 00:24:29,126 division and here we will do a division 596 00:24:27,077 --> 00:24:31,094 but what if they didn't enter anything I 597 00:24:30,026 --> 00:24:33,029 order they entered something that wasn't 598 00:24:31,094 --> 00:24:34,181 one of those things well in that 599 00:24:33,056 --> 00:24:37,112 situation there is a Ketchel and that 600 00:24:35,081 --> 00:24:39,116 catch-all is known as else so in that 601 00:24:38,012 --> 00:24:41,015 situation we're going to come in and 602 00:24:40,016 --> 00:24:45,019 we're going to print a different message 603 00:24:41,042 --> 00:24:49,067 that is going to say use either plus 604 00:24:45,046 --> 00:24:51,140 minus multiplication or division next 605 00:24:49,067 --> 00:24:54,089 time and there we are and that is all 606 00:24:52,004 --> 00:24:56,102 that we need to do here so we're going 607 00:24:54,089 --> 00:24:58,124 to save that and we are going to run it 608 00:24:57,038 --> 00:25:01,043 and they can come in here and go enter 609 00:24:59,024 --> 00:25:02,120 calculation look at me being silly I 610 00:25:01,043 --> 00:25:04,139 didn't come in here and put a space in 611 00:25:03,002 --> 00:25:07,019 there and your calculation let's save 612 00:25:05,039 --> 00:25:09,095 that let's run it again enter 613 00:25:07,037 --> 00:25:12,065 calculation and we can come in and say 5 614 00:25:09,095 --> 00:25:14,126 plus 4 and it's going to automatically 615 00:25:12,065 --> 00:25:18,116 perform at that calculation for us we'll 616 00:25:15,026 --> 00:25:20,108 also be able to go 5 times 4 get exactly 617 00:25:19,016 --> 00:25:23,018 the same results or well different 618 00:25:21,008 --> 00:25:26,054 results obviously it's multiplication or 619 00:25:23,018 --> 00:25:28,052 we can come in and say 5 and then let's 620 00:25:26,054 --> 00:25:29,063 think you maybe wanted to use modulus 621 00:25:28,052 --> 00:25:31,091 well our program doesn't accept that and 622 00:25:30,044 --> 00:25:33,083 you can see that we get 623 00:25:31,091 --> 00:25:35,132 a little error message there in that 624 00:25:33,083 --> 00:25:38,102 situation it's also very important to 625 00:25:36,032 --> 00:25:41,066 know there are different ways to perform 626 00:25:39,002 --> 00:25:43,067 conditions as you're going to see as the 627 00:25:41,066 --> 00:25:45,110 tutorial continues you're also going to 628 00:25:43,067 --> 00:25:48,104 be able to check if a value is greater 629 00:25:46,001 --> 00:25:52,028 than less than greater than or equal to 630 00:25:49,004 --> 00:25:53,087 less than or equal to or not equal to 631 00:25:52,037 --> 00:25:55,073 and that is weird 632 00:25:53,087 --> 00:25:57,173 but that is the way you check if two 633 00:25:55,073 --> 00:25:59,135 things are not equal to and now what 634 00:25:58,073 --> 00:26:01,166 we're going to do is we're going to do 635 00:26:00,035 --> 00:26:05,042 another example and then you're going to 636 00:26:02,066 --> 00:26:06,119 get another program problem that you're 637 00:26:05,042 --> 00:26:08,138 going to have to work through in this 638 00:26:07,019 --> 00:26:12,038 example what we're basically going to do 639 00:26:09,038 --> 00:26:13,130 is decide if a birthday is important or 640 00:26:12,038 --> 00:26:15,131 not yes I know it's silly but whatever 641 00:26:14,003 --> 00:26:19,045 what we're going to do is we're going to 642 00:26:16,031 --> 00:26:24,032 go and say something like we'll provide 643 00:26:19,072 --> 00:26:25,130 different outputs based on age and 644 00:26:24,032 --> 00:26:28,073 there's going to be different conditions 645 00:26:26,003 --> 00:26:30,062 that we have if the age is one through 646 00:26:28,073 --> 00:26:32,084 eighteen while those are very important 647 00:26:30,089 --> 00:26:34,145 so we're going to print out on the 648 00:26:32,084 --> 00:26:37,106 screen that they are important we are 649 00:26:35,045 --> 00:26:40,082 then also going to come in here and in 650 00:26:38,006 --> 00:26:44,087 some countries if you are the age of 21 651 00:26:40,082 --> 00:26:46,160 or 50 or you have an age that is greater 652 00:26:44,087 --> 00:26:50,096 than 65 that is also considered 653 00:26:47,006 --> 00:26:52,013 important and so we will act as if they 654 00:26:50,096 --> 00:26:55,127 are important and then finally all the 655 00:26:53,003 --> 00:26:59,005 other poor people myself included we're 656 00:26:56,027 --> 00:27:01,106 going to say that their birthday is not 657 00:26:59,032 --> 00:27:03,077 important I'm sorry about that but 658 00:27:02,006 --> 00:27:06,023 that's just what I came up with for an 659 00:27:03,077 --> 00:27:07,139 example to mainly show you how to use 660 00:27:06,023 --> 00:27:09,119 logical operators and you're going to 661 00:27:08,039 --> 00:27:12,041 see more of those here in a second so 662 00:27:10,019 --> 00:27:13,067 basically what we want to do here is I'm 663 00:27:12,059 --> 00:27:15,092 going to show you a new way to 664 00:27:13,067 --> 00:27:18,083 automatically convert the string that we 665 00:27:15,092 --> 00:27:20,186 get from input into an integer but what 666 00:27:18,083 --> 00:27:25,130 we want to do is we want to receive age 667 00:27:21,086 --> 00:27:28,094 and store in a variable called age and 668 00:27:26,003 --> 00:27:30,065 then after we do that we are going to 669 00:27:28,094 --> 00:27:32,153 say we're going to use an if statement 670 00:27:30,092 --> 00:27:39,163 again and we're going to say if age is 671 00:27:33,053 --> 00:27:41,060 both greater than or equal to 1 and less 672 00:27:40,063 --> 00:27:46,085 than 673 00:27:42,023 --> 00:27:49,088 or equal to 18 we want to print the 674 00:27:46,085 --> 00:27:50,132 important things so important what else 675 00:27:49,088 --> 00:27:53,170 do we want to do here with our if 676 00:27:51,032 --> 00:27:59,114 statements well we want to say if age is 677 00:27:54,007 --> 00:28:03,053 either 21 or 50 then it's going to be 678 00:28:00,014 --> 00:28:06,017 important also and then we can also them 679 00:28:04,016 --> 00:28:07,019 doing this mainly separately just so I 680 00:28:06,017 --> 00:28:11,018 can show you something else that's neat 681 00:28:07,046 --> 00:28:16,103 we can say that we want to check if age 682 00:28:11,027 --> 00:28:20,039 is less than 65 and then we're going to 683 00:28:17,003 --> 00:28:22,082 use a nifty tool to convert true to 684 00:28:20,039 --> 00:28:25,136 false all right and you're going to see 685 00:28:22,082 --> 00:28:27,083 that and vice versa that tool you're 686 00:28:26,036 --> 00:28:29,048 going to see in a second and that's it 687 00:28:27,092 --> 00:28:30,179 and of course these are all going to 688 00:28:29,048 --> 00:28:33,086 print the message important important 689 00:28:31,079 --> 00:28:35,170 and then we're also going to have 690 00:28:33,086 --> 00:28:38,153 another thing that's going to say not 691 00:28:36,007 --> 00:28:41,096 important for everybody else and that's 692 00:28:39,053 --> 00:28:44,102 going to be our else default so we want 693 00:28:42,059 --> 00:28:47,084 to receive the age and we want to store 694 00:28:45,002 --> 00:28:50,050 it well we are going to call age this 695 00:28:47,084 --> 00:28:52,175 time like I said if you want to 696 00:28:50,005 --> 00:28:56,006 automatically convert the string that 697 00:28:53,075 --> 00:28:57,104 they input into an integer you can use 698 00:28:56,051 --> 00:28:59,120 eval you can do a whole bunch of things 699 00:28:58,004 --> 00:29:02,051 with eval but with this you just refer 700 00:29:00,002 --> 00:29:04,085 to it as evaluate it's going to allow 701 00:29:02,051 --> 00:29:07,097 you to be able to automatically convert 702 00:29:05,003 --> 00:29:10,028 strings into integers in this situation 703 00:29:07,097 --> 00:29:10,151 so that's eval and it's pretty cool and 704 00:29:10,028 --> 00:29:13,109 you're going to see it do even cooler 705 00:29:11,051 --> 00:29:15,095 things later on we are then going to use 706 00:29:14,009 --> 00:29:18,026 what are called logical operators and 707 00:29:15,095 --> 00:29:19,160 they allow you to stack the conditional 708 00:29:18,026 --> 00:29:21,080 operators like the equals to not equals 709 00:29:20,006 --> 00:29:23,024 to greater than and greater than or 710 00:29:21,008 --> 00:29:27,023 equal to and all those guys you're going 711 00:29:23,078 --> 00:29:28,087 to have and that is one of what are 712 00:29:27,095 --> 00:29:34,102 called the logical operators and 713 00:29:29,068 --> 00:29:38,129 basically if both conditions are true it 714 00:29:35,065 --> 00:29:43,114 returns true you're also going to have 715 00:29:39,029 --> 00:29:47,114 or and with or if either condition is 716 00:29:44,014 --> 00:29:50,090 true then you get true as a result and 717 00:29:48,014 --> 00:29:54,032 then finally you're going to have nots 718 00:29:50,009 --> 00:29:54,060 and basically naught is going to convert 719 00:29:54,032 --> 00:29:59,037 a 720 00:29:55,041 --> 00:30:00,117 true condition into a false so if you 721 00:29:59,082 --> 00:30:01,146 give it false it's going to return true 722 00:30:01,017 --> 00:30:04,083 if you give it true it's going to return 723 00:30:02,046 --> 00:30:06,120 false that's what it does all right so 724 00:30:04,083 --> 00:30:08,139 we received our age here and now let's 725 00:30:07,002 --> 00:30:11,040 get down here and let's start using the 726 00:30:09,039 --> 00:30:12,048 logical and conditional operators that I 727 00:30:11,058 --> 00:30:14,064 talked about already so here we are 728 00:30:13,029 --> 00:30:18,057 going to convert this we're going to say 729 00:30:15,018 --> 00:30:20,037 if age we're comparing two conditions 730 00:30:18,057 --> 00:30:21,081 here so throw those little parentheses 731 00:30:20,037 --> 00:30:23,094 around there to keep everything neat if 732 00:30:21,081 --> 00:30:25,095 the age is greater than or equal to one 733 00:30:23,094 --> 00:30:29,109 then we want to use the logical operator 734 00:30:25,095 --> 00:30:32,190 and we want to say if the age is less 735 00:30:30,009 --> 00:30:36,066 than or equal to 18 in that situation 736 00:30:33,009 --> 00:30:37,104 you are important so we're going to tell 737 00:30:36,066 --> 00:30:41,082 the whole world that this is an 738 00:30:38,085 --> 00:30:43,173 important birthday then we're going to 739 00:30:41,082 --> 00:30:46,176 come down here and we're going to say LF 740 00:30:44,073 --> 00:30:49,092 because this is going to be a different 741 00:30:47,076 --> 00:30:55,131 condition and we're going to again say 742 00:30:49,092 --> 00:30:57,096 age is equal to 21 or age is equal to 50 743 00:30:56,031 --> 00:31:00,042 so that's going to cover either one of 744 00:30:58,032 --> 00:31:02,118 those guys and that's why that's good 745 00:31:00,042 --> 00:31:05,046 and once again you are deemed an 746 00:31:03,018 --> 00:31:08,019 important person or a person that has an 747 00:31:05,082 --> 00:31:09,120 important birthday so we'll throw that 748 00:31:08,019 --> 00:31:12,045 in there then what we're going to do is 749 00:31:10,002 --> 00:31:15,024 the snazzy little thing in which we are 750 00:31:12,045 --> 00:31:16,110 going to convert in this situation what 751 00:31:15,042 --> 00:31:18,042 you would normally do here I'm just like 752 00:31:17,001 --> 00:31:21,006 I said I'm looking for a reason to do 753 00:31:18,042 --> 00:31:24,087 this else if I would normally do age is 754 00:31:21,006 --> 00:31:26,028 greater than 65 like that and then print 755 00:31:24,087 --> 00:31:28,101 important birthday but what I'm going to 756 00:31:26,082 --> 00:31:31,110 do is I'm going to change this to a less 757 00:31:29,001 --> 00:31:34,002 than and then I'm going to throw not in 758 00:31:32,001 --> 00:31:35,082 front of it and that is going to allow 759 00:31:34,002 --> 00:31:38,037 me to get the opposite and you're going 760 00:31:35,091 --> 00:31:39,120 to see not being used for things that 761 00:31:38,037 --> 00:31:41,088 are a little bit more interesting and 762 00:31:40,002 --> 00:31:43,044 useful than that but I just wanted to 763 00:31:41,088 --> 00:31:44,184 show you what not does converts false as 764 00:31:43,062 --> 00:31:47,121 in the true stars trues and falses okay 765 00:31:45,084 --> 00:31:50,160 and then finally we get to the end here 766 00:31:48,021 --> 00:31:53,088 and we want to say else and then we want 767 00:31:51,006 --> 00:31:56,073 to make the whole world sad by saying 768 00:31:53,088 --> 00:31:58,122 not important birthday or let's be a 769 00:31:57,027 --> 00:32:00,066 little bit nice and let's just say sorry 770 00:31:59,022 --> 00:32:03,048 not 771 00:32:00,066 --> 00:32:04,155 important okay so at least we said sorry 772 00:32:03,048 --> 00:32:07,131 there we go we saved it we're going to 773 00:32:05,055 --> 00:32:10,059 run it come down here to the Aged area 774 00:32:08,031 --> 00:32:12,060 and we're going to enter something like 775 00:32:10,059 --> 00:32:13,101 twelve important birthday comes back 776 00:32:12,006 --> 00:32:16,008 let's run it again now we're going to 777 00:32:14,001 --> 00:32:18,036 type in twenty opps sorry not important 778 00:32:16,008 --> 00:32:20,046 then we're going to run it again and 779 00:32:18,036 --> 00:32:23,049 we're going to type in 65 enter 780 00:32:21,018 --> 00:32:25,040 important birthday and we can continue 781 00:32:23,049 --> 00:32:28,074 doing this over and over again until 782 00:32:25,004 --> 00:32:30,033 infinity and there you can see exactly 783 00:32:28,074 --> 00:32:32,130 how that works how conditional operators 784 00:32:30,069 --> 00:32:35,082 and logical operators work together to 785 00:32:33,003 --> 00:32:38,094 allow you to combine condition and now 786 00:32:35,082 --> 00:32:40,170 it is time for a problem this problem is 787 00:32:39,021 --> 00:32:43,068 going to be basically a person is going 788 00:32:41,007 --> 00:32:45,039 to enter their age and then you are 789 00:32:43,068 --> 00:32:47,139 going to determine what grade they 790 00:32:46,002 --> 00:32:53,055 should be in so if we think about this 791 00:32:48,039 --> 00:32:55,134 problem if the age is five you are going 792 00:32:53,055 --> 00:32:59,112 to print out that the person needs to go 793 00:32:56,034 --> 00:33:01,041 to kindergarten and then what you're 794 00:33:00,012 --> 00:33:08,031 going to do is you're going to say ages 795 00:33:02,004 --> 00:33:12,087 6 through 17 in that situation goes to 796 00:33:08,031 --> 00:33:14,034 grades 1 through 12 and you should be 797 00:33:12,087 --> 00:33:16,095 able to handle those with one condition 798 00:33:14,061 --> 00:33:23,061 I'll have a whole bunch of them and then 799 00:33:16,095 --> 00:33:24,177 if age is greater than 17 say go to 800 00:33:23,061 --> 00:33:26,118 college and then there's going to be 801 00:33:25,077 --> 00:33:27,159 another condition you're going to have 802 00:33:27,018 --> 00:33:30,093 to handle which I'm going to let it to 803 00:33:28,059 --> 00:33:34,100 you to figure that one out and basically 804 00:33:30,093 --> 00:33:38,189 your goal in this situation is to try to 805 00:33:35,000 --> 00:33:43,026 complete this program with 10 or less 806 00:33:39,089 --> 00:33:44,145 lines so there you go pause the video 807 00:33:43,026 --> 00:33:46,101 refer to your cheat sheet and see if you 808 00:33:45,045 --> 00:33:50,046 can solve this little problem we got 809 00:33:47,001 --> 00:33:52,038 here alright so we are back again what 810 00:33:50,055 --> 00:33:56,055 are we going to do we're going to ask 811 00:33:52,038 --> 00:33:59,040 for the age and then we're going to 812 00:33:56,055 --> 00:34:00,066 handle this is the one that I told you 813 00:33:59,004 --> 00:34:04,020 you're going to have to find on your own 814 00:34:00,066 --> 00:34:06,075 if age is less than five we don't want 815 00:34:04,056 --> 00:34:09,085 any toddlers going to school we are then 816 00:34:06,075 --> 00:34:13,087 also special output 817 00:34:09,085 --> 00:34:15,094 just for age five being the kindergarten 818 00:34:13,087 --> 00:34:18,184 thing that we had there before and here 819 00:34:16,075 --> 00:34:26,167 what we're going to do is since a number 820 00:34:19,084 --> 00:34:31,168 is the result for ages 6 through 17 we 821 00:34:27,067 --> 00:34:35,158 can check them all with one condition 822 00:34:32,068 --> 00:34:37,141 okay may not I may have got that one it 823 00:34:36,058 --> 00:34:40,093 doesn't really matter and then what 824 00:34:38,041 --> 00:34:42,100 we're going to do is handle everyone 825 00:34:40,093 --> 00:34:44,107 else so we're going to come in here and 826 00:34:43,000 --> 00:34:48,013 I'm wondering if maybe whenever you were 827 00:34:45,007 --> 00:34:49,081 asking for the age if you use eval you 828 00:34:48,013 --> 00:34:51,040 remember to eval no problem if he 829 00:34:49,081 --> 00:34:53,143 doesn't then we're going to come in and 830 00:34:51,004 --> 00:34:55,069 we're going to say enter age and in this 831 00:34:54,043 --> 00:34:57,043 situation I'm going to remember to put a 832 00:34:56,005 --> 00:34:58,084 space inside of there 833 00:34:57,043 --> 00:35:01,066 then we come down here and we're going 834 00:34:58,084 --> 00:35:05,119 to handle if age is less than 5 so if 835 00:35:01,066 --> 00:35:08,098 age is less than 5 we are going to print 836 00:35:06,019 --> 00:35:14,020 out a message and that message is going 837 00:35:08,098 --> 00:35:16,162 to be too young for school and then we 838 00:35:14,002 --> 00:35:19,063 need to come down here and do LF and in 839 00:35:17,062 --> 00:35:23,095 this situation we're going to say if age 840 00:35:19,081 --> 00:35:25,144 is equal to 5 we're going to print on 841 00:35:23,095 --> 00:35:29,134 another message and this message is 842 00:35:26,044 --> 00:35:32,113 going to be go to kindergarten and then 843 00:35:30,034 --> 00:35:35,041 we're going to come down here and go LF 844 00:35:33,013 --> 00:35:37,060 and in this situation we're going to use 845 00:35:35,041 --> 00:35:39,100 a conditional as well as a logical 846 00:35:37,006 --> 00:35:43,030 operator we're going to say LLL if age 847 00:35:40,000 --> 00:35:47,029 is greater than 5 number 5 is being 848 00:35:43,084 --> 00:35:49,180 taken up with kindergarten and age is 849 00:35:47,029 --> 00:35:53,122 less than or equal to 17 in that 850 00:35:50,008 --> 00:35:54,085 situation we're going to print out well 851 00:35:54,022 --> 00:35:57,073 what we're going to do first do a 852 00:35:55,057 --> 00:36:00,115 calculation we're going to say grade is 853 00:35:57,073 --> 00:36:02,074 equal to age minus 5 and if you didn't 854 00:36:01,015 --> 00:36:03,093 get this don't worry about it you're 855 00:36:02,074 --> 00:36:06,103 going to get better and better as you 856 00:36:03,093 --> 00:36:08,095 see examples and how they work so you're 857 00:36:07,003 --> 00:36:11,052 going to say go to throw in the curly 858 00:36:09,013 --> 00:36:13,039 bracket grade 859 00:36:11,079 --> 00:36:15,144 then after this we are going to call for 860 00:36:13,039 --> 00:36:17,448 Matt throw in the right information and 861 00:36:15,729 --> 00:36:19,785 that's going to be grade like that and 862 00:36:17,799 --> 00:36:21,897 then otherwise we're going to come down 863 00:36:20,289 --> 00:36:25,660 here and go else and we're going to 864 00:36:22,779 --> 00:36:26,811 print go to college and we're going to 865 00:36:25,066 --> 00:36:30,915 save it and we're going to run it and 866 00:36:27,099 --> 00:36:33,171 enter age let's type in 17 go to 12th 867 00:36:31,509 --> 00:36:35,565 grade lamp great I should reword that 868 00:36:33,819 --> 00:36:36,891 and said grade 12 whatever I'm writing 869 00:36:36,069 --> 00:36:40,134 these programs out of my head that's why 870 00:36:37,539 --> 00:36:42,606 I didn't think of that type in five go 871 00:36:40,719 -->
