Day 9 of #100DaysOfCode in Python: Mastering the Art of Modular Programming with Python Modules

Greetings on Day 9 of your Python journey with #100DaysOfCode! Every day, every line of code written and every concept learned is a victory in itself. Today, we will dive deep into the world of modules. This is an important step towards writing clean, maintainable, and reusable code.

Understanding Python Modules

In Python, a module is a file containing Python statements and definitions. For example, a file containing Python code, like functions, variables, and classes, which can be imported and used in other Python files.

Why Modules?

1. Code Reusability: Write once, use everywhere.
2. Namespace Partitioning: Avoid naming conflicts between your code and library or between libraries.
3. Code Organization: Break down large programs into smaller, manageable, and organized files.

Creating a Module

Creating a module is as simple as writing a Python script. Let’s create a simple module containing a variable, a function, and a class.

Filename: my_module.py

# Variable
module_variable = "I'm a module variable"

# Function
def…
