🐍 Python Assignment 5 – Loops & Pattern Programming

A collection of beginner-to-intermediate Python programs focused on mastering loops, nested loops, pattern printing, functions, string manipulation, and algorithmic thinking.

This assignment emphasizes understanding the logic behind iteration, rather than simply memorizing syntax. Every problem is implemented using appropriate looping techniques (for and while) and demonstrates multiple approaches wherever applicable.
