Importing Modules in Python

In Python, modules are files containing Python definitions and statements. A module allows you to logically organize your Python code into different files. The most basic way to import a module is by using the import statement. For example:

import math

This imports the entire math module, and you can access its functions like this:

print(math.sqrt(25))

You can also import specific functions using from ... import ...:

from math import sqrt
print(sqrt(25))

Modules help you reuse code, making your programs modular and easy to manage.
