So welcome to the libraries and modules section.
And of course in here, you're going to learn how to work with them.
But what exactly are libraries and modules think of them
as basically programs that have already been written by other Python developers.
Keep in mind that the Python community is a big one.
You have developers who have written their own kinds of code,
maybe there's a programmer out there who has already written
their own code on how to encrypt the password.
So instead of you having to write such a program from scratch,
you can simply import that program onto your own program
and then modify to do something else, right?
That's kind of the whole point of working with libraries and modules.
So in this section,
you're going to learn the different types of libraries and modules out there,
the differences between libraries and modules.
And of course,
we're also going to have different challenges and coding exercises as well.
So without wasting any more time, let's jump right in.
