Python Crash Course, 4th Edition

The world's bestselling Python introduction, with 3 million copies sold in 16 languages, is fully revised for Python 3.15, modern tooling, and the age of AI coding assistants.

Three complete hands-on projects (a game, a data visualization tool, and a deployable web application) anchor a structured, honest approach to learning to code alongside AI.

Three million copies. Sixteen languages. Four editions. Python Crash Course is the book that taught a generation to program, and the 4th edition meets the moment it's publishing into.
