00:00:00,000 --> 00:00:04,859

Hey welcome to this new lecture and in

this lecture I'm going to show you how

3

00:00:04,859 --> 00:00:12,059

to create and execute a Python program

on a Mac computer, so if you are a

5

00:00:12,059 --> 00:00:17,520

Windows user please skip this lecture.

And so in the previous lecture I showed

7

00:00:17,520 --> 00:00:25,080

you how to install Python 3 and also how

to launch a Python 3 interactive

9

00:00:25,080 --> 00:00:33,809

Session, so which is good for executing

and testing out code so like that line.

11

00:00:33,809 --> 00:00:43,410

Like my line, but if you quit the terminal

you're going to lose that code, so you

13

00:00:43,410 --> 00:00:49,800

want to find out a way to save that code

in a file so that you can develop your

15

00:00:49,800 --> 00:00:56,010

program step by step, so you can go back

to your code, add the code, modify it, and

17

00:00:56,010 --> 00:01:01,379

most importantly you can execute

multiple lines at once instead of

19

00:01:01,379 --> 00:01:06,659

executing line by line interactively.

So let's go ahead and do that.

21

00:01:06,659 --> 00:01:11,700

Normally you need to figure out,

to create a directory where you want to

23

00:01:11,700 --> 00:01:17,850

save your program, so I'm going to create

this folder in here and this is empty

25

00:01:17,850 --> 00:01:25,590

for now, so I'm going to create a

file there. There may be different ways

27

00:01:25,590 --> 00:01:32,189

of creating a Python file all but I prefer

to do it via the terminal.

29

00:01:32,189 --> 00:01:37,560

So currently you do PWD, that will print

out the current directory of the terminal,

31

00:01:37,560 --> 00:01:43,049

so the terminal is an app and it is

opened in the current directory, in a certain

33

00:01:43,049 --> 00:01:50,399

directory which is this on for the

moment. If you do ls you will see the

35

00:01:50,399 --> 00:01:56,939

directories and files or the current

Directory, so users admin has this

37

00:01:56,939 --> 00:02:03,090

directors, has these folders so if you

want to go to the desktop folder,

39

00:02:03,090 --> 00:02:08,080

you'd want to do

desktop or you can use the Tab for auto

41

00:02:08,080 --> 00:02:16,360

Completion, so the tab key and then Un Tab.

That will take you to the

43

00:02:16,360 --> 00:02:24,250

untitled folder. Execute and I'll see

that your current folder is the untitled

45

00:02:24,250 --> 00:02:32,020

folder and that means you can go ahead

and create a file now. Let's say touch my

47

00:02:32,020 --> 00:02:42,070

program dot py, so you can give it

any name that you want. Execute and that

49

00:02:42,070 --> 00:02:49,420

will create an empty file which for now

you can go ahead and edit it with text

51

00:02:49,420 --> 00:02:54,160

edit for example. Later on we're going

to install Atom editor which is much

53

00:02:54,160 --> 00:02:59,709

more advanced than this simple editor

but for now this should be enough to

55

00:02:59,709 --> 00:03:06,580

just get you started to get you the

idea on how to execute a Python program

57

00:03:06,580 --> 00:03:12,340

so let create code for the program.

This program will simply

59

00:03:12,340 --> 00:03:20,230

print out the hello text so you need, you

use this print keyword and then you use

61

00:03:20,230 --> 00:03:28,600

double quotes and then the text hello and

then another double quote to close the

63

00:03:28,600 --> 00:03:32,760

text and then a closing bracket.

65

00:03:46,470 --> 00:03:56,520

CTRL S to save, exit text edit and then

go back to the terminal and what you do

67

00:03:56,520 --> 00:04:00,930

here now to execute your program, the

program that you just created, you use the

69

00:04:00,930 --> 00:04:07,200

Python 3 command and then my, you can

type my program dot py or you can use

71

00:04:07,200 --> 00:04:14,760

tab to autocomplete the name, enter to

execute and you get the output of the program.

73

00:04:14,760 --> 00:04:20,040

Print it out in the terminal so in this

case the output is hello and yeah that's how

75

00:04:20,040 --> 00:04:24,570

you create and execute a program on Mac

and similarly you can go ahead and

77

00:04:24,570 --> 00:04:31,050

create other Python programs in here just

as we did with my program dot py. I can also

79

00:04:31,050 --> 00:04:35,730

show you a quick way to actually open

the terminal in this current directory

81

00:04:35,730 --> 00:04:42,690

without having to do CD and try the

path name, so let's do that.

83

00:04:42,690 --> 00:04:50,460

You go here, system preferences, so this is a

one time configuration. Go to keyboard.

85

00:04:50,460 --> 00:05:03,150

Shortcuts and then in the shortcuts tab

you go to services, scroll down and see

87

00:05:03,150 --> 00:05:08,070

you probably have this option

unchecked, so you want to make sure you

89

00:05:08,070 --> 00:05:13,590

have checked the new terminal at folder

option just like I have it here, so make

91

00:05:13,590 --> 00:05:20,490

sure make sure that is checked. Close

this and then what you do is to open the

93

00:05:20,490 --> 00:05:25,350

terminal in a current folder, in a

specific folder you right click on

95

00:05:25,350 --> 00:05:34,110

folder and then go to New Terminal at

Folder and now what you do is Python 3

97

00:05:34,110 --> 00:05:39,390

Myprogram.py, execute and you get the

Output, so that's a quick way to open

99

00:05:39,390 --> 00:05:44,100

the terminal in a specific folder and

yeah that's about this lecture.

101

00:05:44,100 --> 00:05:50,210

I hope everything went smoothly and I'll

talk to you later. Thanks.
