What problem does it solve?
This Skill eliminates the frustration of writing inconsistent, non-idiomatic Python code that violates PEP 8 standards, lacks proper type hints, and ignores established best practices, which leads to bugs, technical debt, and codebases that are hard for teams to maintain.
Core Features & Use Cases
- Pythonic Idiom Guidance: Clear examples and rules for EAFP, comprehensions, generators, and other idiomatic Python patterns to write code that is intuitive for other Python developers.
- Type Hint & Error Handling Standards: Best practices for type annotations, custom exception hierarchies, and exception chaining to improve code reliability and debuggability.
- Production Project Structure: Templates and conventions for organizing Python packages, integrating essential development tooling (black, ruff, mypy, pytest), and optimizing performance with memory-efficient patterns.
- Use Case: A developer refactoring a legacy Python data processing script can use this Skill to update the code to follow modern type hint standards, replace manual loops with efficient comprehensions, and add proper error handling for edge cases.
Quick Start
Use the python-patterns skill to review your existing Python script and suggest specific improvements for readability, type safety, and adherence to PEP 8 standards.
