This repository documents my journey learning Python from scratch.
From the very first print("Hello, World!") to building classes, handling files, and writing programs that actually do useful things — every file here represents a real step in my learning process. The notes and exercises are written the way I actually understood them, so if you're also starting out, hopefully they make sense to you too.
13 chapters, each with its own documentation and runnable scripts.

python PythonBasics/<chapter>/<script_name>.pyNo external dependencies required — just Python 3.x.
Some scripts use modules from the standard library (random, turtle, datetime) — these ship with Python, no pip install needed.
