Modules are separate files containing Python code such as functions, classes, or variables. Importing modules enables you to extend your program's functionality by using external libraries and frameworks.

import module_name
from module_name import specific_function_or_class

Example:

import math
print(math.sqrt(16))  # Output: 4.0
