00:00:00,000 --> 00:00:04,110

Hello there and welcome to this new

lecture! In this lecture I'll show you

3

00:00:04,110 --> 00:00:09,240

how to set up Python in your computer.

Specifically these instructions are for

5

00:00:09,240 --> 00:00:15,210

Windows users so if you are a Mac or

Linux user you can skip this lecture

7

00:00:15,210 --> 00:00:18,300

and you can go to the next lecture where

I'll show you how to set up Python on a

9

00:00:18,300 --> 00:00:24,420

Mac and instructions also work for Linux

users so Windows users please follow if

11

00:00:24,420 --> 00:00:29,490

you haven't installed Python yet, we're

going to download and install python and

13

00:00:29,490 --> 00:00:36,630

also try Python out. And so you go to

python.org that's the official Python

15

00:00:36,630 --> 00:00:41,760

website and you go to downloads and here

you'll see the latest Python version.

17

00:00:41,760 --> 00:00:51,600

Currently it is 3.6.0.

Just click that and save file.

19

00:00:51,600 --> 00:00:57,750

Also notice that there's also a version

of Python 2 so Python 2.7 to be exact

21

00:00:57,750 --> 00:01:05,369

but Python 2 is not being supported

anymore after 2020 so Python 2 is slowly

23

00:01:05,369 --> 00:01:12,780

retiring so it's advisable to use Python

3 this one in here and once you have

25

00:01:12,780 --> 00:01:22,080

downloaded the dot exe file just click it.

Run. You can choose to install it in the

27

00:01:22,080 --> 00:01:27,509

default directory but you can also do a

customized installation if you want to

29

00:01:27,509 --> 00:01:32,700

change the directory, anyway make sure

you have checked this option at Python

31

00:01:32,700 --> 00:01:40,320

3.6 to PATH so I'm going to go with the

default installation process. Yeah that

33

00:01:40,320 --> 00:01:45,329

was it. Set up was successful. You can

close the window now and we can go ahead

35

00:01:45,329 --> 00:01:52,079

and open Pythom so how do we do that

on windows? Well we can press the

37

00:01:52,079 --> 00:01:58,590

Windows key button, so we're talking

about the Win key. By pressing it you

39

00:01:58,590 --> 00:02:03,990

will be able to search on the start

button, alternatively you can simply go

41

00:02:03,990 --> 00:02:10,289

to the start button, click it and then

type cmd and then click on c armed.exe

43

00:02:10,289 --> 00:02:15,470

and that will open the windows command prompt.

And so this is like the terminal

45

00:02:15,470 --> 00:02:21,110

on Mac or Linux. On Mac and Linux it

is referred to as the terminal on

47

00:02:21,110 --> 00:02:26,510

Windows it is referred to as a comand

prompt or command line. To open Python all

49

00:02:26,510 --> 00:02:32,930

you have to do is type in Python and

that will open an interactive session of

51

00:02:32,930 --> 00:02:39,650

Python and an interactive session is

best for testing out so here you can

53

00:02:39,650 --> 00:02:46,970

write lines of code one by one like that

and you promptly get the results in here.

55

00:02:46,970 --> 00:02:53,900

So this is why we call it interactive, but

you cannot, it's not very appropriate to

57

00:02:53,900 --> 00:02:59,150

write multiple lines of code, so let's

say you have a program that has 10 lines

59

00:02:59,150 --> 00:03:05,269

of code and in that case you'd want to

write those lines in a file, in a Python

61

00:03:05,269 --> 00:03:09,290

file but we will cover that later and

this is the interactive shell this is

63

00:03:09,290 --> 00:03:14,030

good for testing, so before you do a

program you are not sure about certain

65

00:03:14,030 --> 00:03:18,829

aspects, certain commands that you

want to include, certain keywords that

67

00:03:18,829 --> 00:03:23,239

you want including in your program so you

test things out in here very quickly.

69

00:03:23,239 --> 00:03:28,220

This is very efficient and it's also

good for learning. To exit the

71

00:03:28,220 --> 00:03:36,290

interactive shell you press exit and

brackets, open and closing brackets.

73

00:03:36,290 --> 00:03:43,220

Now something you maybe, you probably noted

was that the Python that I opened was version

75

00:03:43,220 --> 00:03:51,709

3.5.2 but why is that because I

installed Python 3.6 in here, 3.6, so why did

77

00:03:51,709 --> 00:03:55,010

I get five Python 3.5.2?

Well the answer is that I already had

79

00:03:55,010 --> 00:04:01,310

Python 3.5.2

installed on my Windows so in other words

81

00:04:01,310 --> 00:04:09,919

before I install Python 3.6 I could

trigger a Python shell like that so the

83

00:04:09,919 --> 00:04:15,260

question is how do I run Python 3.6 now?

Well the first thing you should know is

85

00:04:15,260 --> 00:04:20,690

that there is no problem having multiple

Python installations in your system, the

87

00:04:20,690 --> 00:04:25,880

key here is that you have to assign

different commands to each of your

89

00:04:25,880 --> 00:04:28,430

Python

instalations so for instance Python 3.5.2

91

00:04:28,430 --> 00:04:32,540

has these commands

to run Python. Now for Python 3.6

93

00:04:32,540 --> 00:04:39,770

we need to assign another

command and I'll go and search for the

95

00:04:39,770 --> 00:04:48,800

installation directory of

Python 3.6 so open that and now Windows

97

00:04:48,800 --> 00:04:54,470

when you search for Python, when you

enter the Python command here, Windows is

99

00:04:54,470 --> 00:04:59,450

looking at the path variable, the Windows

path variable and it's searching for

101

00:04:59,450 --> 00:05:05,510

this type of command Python but this

was already occupied by another so by

103

00:05:05,510 --> 00:05:09,530

Python 3.5.2, that's why it

triggers Python 3.5.2,

105

00:05:09,530 --> 00:05:15,980

so in that case you may want to do

trick here, let's say do Python 36 and

107

00:05:15,980 --> 00:05:28,070

restart that command prompt and then

run again python 36 and you get Python 36.

109

00:05:28,070 --> 00:05:37,340

So that's the trick and again of course

you can do operations here and so on

111

00:05:37,340 --> 00:05:43,760

Of course you still have Python 3.5 at

least I have Python 3.5 maybe you don't

113

00:05:43,760 --> 00:05:49,430

because you didn't have any Python

installed just yet, so that's the idea.

115

00:05:49,430 --> 00:05:53,720

On your system if you install Python for

the first time, if you install

117

00:05:53,720 --> 00:05:58,220

Python 3.6 you'll be

able to execute Python with this commands.

119

00:05:58,220 --> 00:06:03,980

Python. If you had an existing Python

installation and you install a new one,

121

00:06:03,980 --> 00:06:12,230

no problem, you can run Python 36 like I did

I hope this was clear and I hope you are

123

00:06:12,230 --> 00:06:18,460

up and running now with Python

And I'll talk to you in the next lectures.
