Exploring Modules and Packages in Python: Building Reusable Code Components
1. What are Modules in Python? In Python, a module is a file containing Python code. It can be a Python file (with .py extension) or a compiled Python file (with .pyc extension). It contains functions, classes, and variables that can be used by other Python programs. Modules help us to organize our code into separate files, which can be used in other programs, making our code more reusable.

Creating a Module To create a module, we simply need to create a Python file with .py extension and add our functions, classes, and variables in it. Example: creat
