Modules and Packages Tutorial

Welcome to the tutorial on Modules and Packages. This guide will help you understand how to use and manage modules and packages in your projects. Modules are a way to organize your code into separate, reusable components, while packages are collections of modules that are distributed together.

What is a Module?

A module is a file containing Python code. It can define functions, classes, and variables. You can import modules into your main Python script to use their functionality.

Example of a Module

Here's a simple example of a module named math_utils.py:

# math_utils.py

def add(x, y):
    return x + y

def subtract(x, y):
    return x - y

What is a Package?

A package is a directory that contains Python modules. It allows you to organize your code into a more structured hierarchy.

Example of a Package

Consider a package named my_package. It contains two modules: module1.py and module2.py.

my_package/
│
├── module1.py
└── module2.py

Importing Modules and Packages

To use a module or package, you need to import it into your Python script.

Importing Modules

import math

print(math.sqrt(16))

Importing Packages

import my_package

my_package.module1.add(5, 3)

Importing Specific Functions or Classes

from math import sqrt

print(sqrt(16))

Best Practices

• Always use descriptive names for your modules and packages.
• Keep your modules and packages organized and well-documented.
• Use version control to manage your code and its dependencies.
