# Python Patterns · yandy-r

> Idiomatic Python patterns, PEP 8 conventions, type hints, dataclasses, context managers, decorators, and best practices for building robust, maintainable Python applications. Use when the user is writing new Python code, reviewing Python code, refactoring Python, designing Python packages/modules, asks "how should I structure this in Python", asks about EAFP vs LBYL, asks about type hints/Protocol/TypeVar/TypeAlias, asks about dataclasses/NamedTuple/slots, asks about context managers and with blocks, asks about decorators or functools, asks about asyncio/threading/multiprocessing tradeoffs, or wants Python idioms and anti-patterns.
