1
00:00:00,009 --> 00:00:02,839
So welcome to the libraries and modules section.

2
00:00:02,849 --> 00:00:06,440
And of course in here, you're going to learn how to work with them.

3
00:00:06,510 --> 00:00:09,430
But what exactly are libraries and modules think of them

4
00:00:09,760 --> 00:00:15,279
as basically programs that have already been written by other Python developers.

5
00:00:15,350 --> 00:00:18,219
Keep in mind that the Python community is a big one.

6
00:00:18,340 --> 00:00:21,059
You have developers who have written their own kinds of code,

7
00:00:21,149 --> 00:00:23,500
maybe there's a programmer out there who has already written

8
00:00:23,510 --> 00:00:26,340
their own code on how to encrypt the password.

9
00:00:26,450 --> 00:00:30,569
So instead of you having to write such a program from scratch,

10
00:00:30,670 --> 00:00:34,340
you can simply import that program onto your own program

11
00:00:34,580 --> 00:00:37,229
and then modify to do something else, right?

12
00:00:37,240 --> 00:00:40,770
That's kind of the whole point of working with libraries and modules.

13
00:00:40,779 --> 00:00:41,740
So in this section,

14
00:00:41,930 --> 00:00:44,630
you're going to learn the different types of libraries and modules out there,

15
00:00:44,639 --> 00:00:46,490
the differences between libraries and modules.

16
00:00:46,659 --> 00:00:47,319
And of course,

17
00:00:47,330 --> 00:00:51,150
we're also going to have different challenges and coding exercises as well.

18
00:00:51,159 --> 00:00:54,200
So without wasting any more time, let's jump right in.
