Introduction

This lesson is part of our complete Python course for beginners. In this lesson, you will learn modules and packages in Python and how to organize and reuse code efficiently.

Understanding modules and packages in Python for beginners is important because large applications require structured and maintainable code.

What are Modules in Python?

A module in Python is a file that contains Python code such as functions, variables, or classes. Modules allow you to reuse code in different programs.

Example:

file: mymodule.py

def greet(name): return “Hello ” + name

Importing Modules

You can use modules in your program using the import statement.

Example:

import mymodule print(mymodule.greet(“John”))

You can also import specific functions:

from mymodule import greet

Built-in Modules in Python

Python provides many built-in modules.

Examples:

• math
• random
• datetime

Example:

import math print(math.sqrt(16))

What are Packages in Python?

A package is a collection of multiple modules organized in folders.

Packages help in structuring large projects.

Example structure:

myproject/ ├── module1.py ├── module2.py └── init.py

Why Modules and Packages are Important

Modules and packages in Python help you:

• Reuse code across projects
• Organize large applications
• Improve code readability

Therefore, understanding modules and packages in Python for beginners is essential.
