Course welcome

Welcome — you're about to learn Python from zero, the language that powers most of today's data science and AI.

This course is free, forever. Every lesson runs right here in your browser: when you see a code box with a Run button, you can press it, change the code, and run it again. You learn by doing, not just reading.

By the end you'll write real programs, work with data, and have the confidence to keep going. No prior experience needed — just curiosity and a little patience.
