Python 3.14.6 documentation

** What is a module in Python? **

In Python, a module is simply a file containing Python code with a .py extension. It allows you to logically group and organise your functions, classes, and variables into separate, manageable files so your code can be easily reused across different programs.

What is a user-defined module in Python

user-defined module in Python is simply a custom .py file that you create yourself to store reusable code, such as functions, classes, or variables. Unlike built-in modules like math or random that come pre-packaged with Python, user-defined modules allow you to break down large programs into smaller, highly manageable pieces.

** What is a predefined module in Python **

A *predefined module *(more commonly known as a built-in module) in Python is a pre-written code file containing functions, classes, and variables that comes pre-installed with the Python software.

*What is the import keyword in Python? *

In Python, the import keyword is used to load and access external modules or packages into your current script. It essentially allows you to reuse code written by others—or code you wrote in another file—without rewriting it from scratch.
