Module 6 Overview

Module 6: Modules and Packages deals with code organization on a larger scale. As your programs grow, keeping all logic in a single file becomes unmanageable. Python allows you to split your code into separate files (modules) and directories (packages).

In this module, we will learn how to create our own modules, structure larger applications using packages, and explore the vast ecosystem of Python’s Standard Library.

Learning Objectives

By the end of this module, you will be able to:

• Import functionality using import, from ... import, and aliases.
• Create and structure your own Custom Modules.
• Organize multiple modules into Packages using __init__.py.
• Avoid Circular Imports and understand how Python finds modules.
• Leverage the power of the Python Standard Library (e.g., os, sys, datetime).
