Now, let’s dive into how to use these modules. Using a module from the standard library is similar to using any other module in your Python program.

import math

math.sqrt(4)  # 2.0

Alternatively, you can import specific functions or objects from a module:

from math import sqrt

sqrt(4)  # 2.0

In the upcoming sections, we will explore each of these essential modules in detail to understand what they offer and how to leverage them in your code.
