hamzalafsioui/python_4_all ? reverse-engineered prompt

Build me a polished Python learning repository that takes someone from absolute basics all the way to beginner friendly AI engineering.

I want it organized as a step by step curriculum with clear lessons, runnable examples, practice exercises, and small mini projects in each section. Start with foundations like variables, control flow, data structures, functions, files, errors, and object oriented programming, then move into testing, debugging, performance, databases, networking, data science basics, and the math needed for AI. For the data and math parts, include interactive Jupyter notebooks with simple plots and examples people can explore on their own.

Make it feel practical and easy to follow, with a clean folder structure, readable explanations, and projects that actually work, like a calculator, guessing game, contact manager, file processor, task manager, web scraper, and simple AI style demos. Keep everything runnable from the repo, and if you need to check current best practices or docs online, go ahead.
