Python Functions Cheatsheet

Functions turn repeated code into named, reusable tools: def and return, parameters and arguments, scope, closures, the flexible *args and **kwargs, lambdas, and error handling. This cheatsheet gathers the whole toolkit on one page, each snippet annotated line by line. Keep it open while you code, or save the image and pin it nearby.

For the full background, read the guide to Python functions.

See you soon.
