0 | 6.18 | hello everyone welcome to this video this tutorial is a python full course | |
6.18 | 9.02 | we are going to be learning python programming from scratch | |
10.38 | 16.46 | so this is a list of everything we're going to be talking about in this video so let me give a | |
16.46 | 22.24 | brief introduction to python so python is one of the fastest growing programming languages in the | |
22.24 | 29.84 | world with python you can go into various fields like machine learning and ai web development and | |
29.84 | 35.92 | plenty others so taking to learn this course and choosing to learn python is a very good decision | |
35.92 | 41.4 | for your programming journey so without wasting any time let's get straight into the tutorial | |
46.74 | 53.8 | so right here i'm just on my browser so we're gonna download python on our laptop so to do this | |
53.8 | 64.52 | i'm just gonna search for download python for windows since i'm on a windows and then i'm gonna | |
64.52 | 72.22 | click on the first link and then right here i see download python 3.9.1 which is the latest version | |
72.22 | 77.72 | so i'm just gonna click on it and then you can see here that it downloaded it automatically | |
78.5 | 83.96 | so i already have python downloaded now what i just need to do is to install it so i'm just gonna | |
83.96 | 92.78 | come into where i saved it and then i'm gonna run it so make sure that when you are installing python | |
92.78 | 98.3 | you must stick this add python to part if not you're just gonna make it more complex than it's supposed | |
98.3 | 107.14 | to be for you so let's click install now yes and so this is just gonna install python | |
107.72 | 116.68 | on our machine it should take a few minutes a couple of minutes to install and i'm gonna be back | |
116.68 | 123.26 | when it's installed finish so right now the setup was successful so as you can see the installation | |
123.26 | 130.26 | has been done so i can just click on close now for me to confirm if i have python installed i'm gonna open | |
130.26 | 137.62 | up my command prompt so here in my command prompt i'm just gonna type python once i type | |
137.62 | 142.62 | it you should open up this shell you might not understand what all this is now but this is just | |
142.62 | 149.56 | to verify if python was truly installed so now that we know we have python installed let's just go ahead | |
149.56 | 157.52 | and install our code editor so python is the programming language but where we are going to code where we are | |
157.52 | 162.68 | going to program everything or the python we're going to do is going to be in a code editor and there are | |
162.68 | 168.08 | various code editors out there we have visual studio code we have pi charm we have sublime text we have | |
168.08 | 174.3 | atom there are countless out there but for this tutorial we're going to be using visual studio code | |
174.3 | 180.78 | so let's go ahead and download it so i can close up my command prompt right now so let me just say that | |
180.78 | 187.52 | if you don't know how to get to your command prompt you can just search for it on your windows search bar | |
188.98 | 198.2 | so right here we can just go back to google and then we can search for let's say download visual studio code | |
199.42 | 205.34 | and i'll just click on the first one so since i'm on a windows i'm going to download the one for windows | |
205.34 | 212.66 | if you are on ubuntu or linux or mac download the one for your os so right now you can see that it is | |
212.66 | 220.48 | downloading so i already have it downloaded i have it on my pc i'm just going to cancel that since i | |
220.48 | 227.62 | already have it downloaded let me just show you the installation process so right here i have it | |
227.62 | 235.82 | downloaded already we just click on enter that's to run it so what it tells me here is that setup has | |
235.82 | 241 | detected that visual studio code is running so this simply means that i already have visual studio code | |
241 | 248.36 | installed on my computer so i'm just going to press cancel but for you as a beginner you want to | |
248.36 | 255.1 | install this as a new software so when we already have this installed we're just going to open up our | |
255.1 | 261.44 | visual studio code and this is what it should look like once you first open it up so now we have | |
261.44 | 267.16 | everything set up we downloaded python and installed it and then we downloaded visual studio code and | |
267.16 | 279.08 | installed it now we can go straight into coding so now that we have everything installed what we just | |
279.08 | 286 | want to do is to create a new file in this file is where we're going to code all our python so in visual | |
286 | 293.14 | studio code we're just going to come into the toolbar and click on new file so once we click on new file | |
293.14 | 300.94 | you can see it automatically has its untitled name but we want to save it by pressing ctrl s and i'm just | |
300.94 | 312.2 | going to save it first of all let me say all files and then now to save it as app dot py so the name of | |
312.2 | 319.9 | the file is app but at the bottom at the file extension i used dot py so anytime we're working with python | |
319.9 | 327.2 | any time we want to create a new python file it must always have the extension dot py that will make | |
327.86 | 333.32 | whatever we're running on know that we are using a python file so now once i save it | |
334.98 | 340.72 | it's updated here and as you can see visual studio code automatically detects the logo of python | |
340.72 | 348.84 | now that's how to save create and save a new python file so this is basically how everything looks like | |
348.84 | 357.06 | in visual studio code on the left hand bar we have a folder bar that's where if we are opening a folder | |
357.06 | 362.22 | this is where we're going to see all the files and folders in there we have this search this | |
363.24 | 369.02 | github we don't need to bother about that for now but this is how visual studio code looks like | |
369.8 | 377.56 | so since we have everything we know how to create a new file what we want to talk about now is the print function | |
378.12 | 385.68 | so in python we have some built-in functions that means some things that are already done automatically | |
385.68 | 391.1 | which we don't need to write too much of code now let's say we just want to print uh | |
391.7 | 397.84 | text to the screen like we just want to show a user like hello world or welcome we're going to use the | |
397.84 | 403.1 | print function you're just going to print a basic text to the screen now for us to do this we're going to | |
403.1 | 410.04 | say print and then we're going to open parenthesis and then we can use single codes or we can also | |
410.04 | 415.58 | use double codes there is no problem here in python but we can just go with single code so you can just | |
415.58 | 422.24 | pick one and go with that so in this code i'm going to write my text and i can say hello world | |
426.72 | 434.1 | now as you can see i have printed hello world and i must make sure i save this file and then for me to | |
434.1 | 440.4 | run this python file for me to see the output of my code i'm going to have to come to the right hand | |
440.4 | 446.62 | corner right here and click on run now once i click on run you see that it opens a new terminal | |
446.62 | 453.36 | automatically and our code is going to be run in this terminal so if you just wait a second we're | |
453.36 | 458.52 | going to see the output of this code you can see right here that we have a low world automatically it | |
458.52 | 462.9 | prints a low world if i say hello world welcome | |
465.72 | 474.38 | and i run it you see it changes and it says hello world welcome so that's how to run a python file | |
475.24 | 483.84 | now let's talk about some more features about this print function now let's say we want to print on a | |
483.84 | 490.38 | new line like hello world and we want this welcome to be on another line we can easily do that we can just | |
490.38 | 491.02 | remove this | |
495.02 | 497.86 | and then on a new line we're just going to print | |
500.56 | 509.38 | welcome exactly the same thing now once i run it you can see it says hello world down here and it | |
509.38 | 516.18 | says welcome so that's how to print on a new line we can also do a lot of things let's say we want to | |
516.18 | 526.3 | add another value to this hello world like let's print a sentence let's say my name is told me and | |
526.3 | 537.28 | then i want to say my age is then i can add a comma right here and say 100 so this will automatically | |
537.28 | 546.46 | tell python that this is a number and it's no more a string just a normal character so now once i run it | |
547.28 | 553.42 | you're gonna see it says my name is tommy my name is 100 with no errors and automatically you see that | |
553.42 | 560.38 | it leaves a space right here right here we didn't leave a space but automatically once we put this | |
560.38 | 568.4 | number here it leaves a space to clarify that if i put don't leave no space and i run it you see that | |
568.4 | 574.22 | the space is still there so that's just a smart feature of python so i think that's gonna be all | |
574.22 | 575.62 | for the print function | |
581.98 | 589.22 | now let's talk about variables in python as you can see here i have three print function the first | |
589.22 | 595.3 | one says tim is a boy the second one says tim is 18 and the third one says tim is from turkey | |
595.88 | 603.36 | so as you can see in the three print functions i'm repeating tim three times now we can use variables | |
603.36 | 611.64 | instead of repeating a particular text now variables are just basically saving a data in the memory of | |
611.64 | 617.66 | python and then we can get that data back by referencing its name so let's see this in action | |
618.56 | 626.48 | let's say above the code i have a variable named name so this name is the name of the variable | |
627.18 | 635.54 | and i'm saying equals to i put single codes and the name is team so name is the name of the variable | |
635.54 | 643.06 | and team is the value assigned to this name so like this we've saved this variable up here | |
643.68 | 650.5 | so we can print that variable once you say print whenever we are printing a variable we don't put | |
650.5 | 656.1 | codes like we do when we are printing a normal string so we can remove the codes and just type the name of | |
656.1 | 662.92 | the variable which is name so now when i run this you are going to see it prints all this and on the | |
662.92 | 669.82 | fourth line it prints team it didn't print name now this is what variable is about it's just basically | |
669.82 | 677.88 | saving a particular data and then referencing it through the variable name so now instead of saying | |
677.88 | 685.76 | team three times we can just replace this team with name and for us to do this right here you see we | |
685.76 | 694.32 | printed only the variable and we didn't have quote but right here we are printing string with quote and | |
694.32 | 700.44 | we also want to print the variable with it so this is called concatenation we are going to join the | |
700.44 | 710.02 | variable and the normal string together to do this let's remove team and we are going to say name which | |
710.02 | 717.48 | is the name of the variable plus the remaining text now once we say name plus is a boy it's going to print | |
717.48 | 727.2 | us team is a boy so we can also do the same right here we just simply remove team and we say name plus | |
727.2 | 735.88 | is 18 we do the same for the third line we'll say name plus is from turkey now once we print this |
