Your Web Development Manual

Python exposes a lot of built-in functionality through its standard library.

Let’s introduce how to use a module of the standard library. You already know how to use modules you create, importing from other files in the program folder.

Well that’s the same with modules provided by the standard library:

import math

math.sqrt(4) # 2.0

or

from math import sqrt

sqrt(4) # 2.0

We’ll soon explore the most important modules individually to understand what we can do with them.
