Python Development

Teaches Claude modern Python 3.10+ idioms like structural pattern matching, PEP 604 union types, and the type keyword for aliases. It covers async/await patterns, context managers, comprehensions, and debugging with pdb, cProfile, and memory profilers. The skill focuses on idiomatic code rather than project setup or testing, which have their own dedicated skills. You get practical examples of SOLID principles, factory and decorator patterns, and performance profiling techniques. It assumes you're writing library code or refactoring existing Python, not running one-off scripts. The pattern matching examples alone make it worth invoking if you're working with Python 3.10 or newer.
