# Python Patterns

Use this skill for Python package structure, idiomatic code, error handling,
dataclasses, and maintainable module design.

## When to Use

- Build a new Python library or CLI.
- Refactor Python modules without changing behavior.
- Choose simple standard-library patterns before adding dependencies.
