The modules and libraries are this beautiful things that you will find when you are programming. These ones help us when we are programing and we need a function that already exists. Like when you need that your program make a random action the only thing that you need to do is import the library random:
As you can see we use one specific function from de library random, that actually have a lot, if you want to se more: Random library
We can have the same result of a module as a library, but the difference between these is that a module is a file that has a lot of functions inside it and is save like a .py file, for other side a library already exist and you only import when you need to use it. In few word, you do and use a module and you only use a library.
When you want a specific function from a module or library you write:
from module/library import specific
