SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires pytest, mypy, black, ruff, and includes references (resource) and scripts (resource) components.

What problem does it solve?

This Skill enhances Python application development by providing tooling for type safety, asynchronous programming, and robust error handling.

Core Features & Use Cases

  • Type Annotations & Validation: Generate code with strict type hints and enforce code correctness through mypy validation.
  • Async Program Support: Write efficient, concurrent I/O-bound Python code with modern async/await patterns.
  • Use Case: Build a production-ready web app with FastAPI, proper testing, and type-checked code that can handle high concurrency and error scenarios.

Quick Start

Use the python-pro skill to create a type-safe async API client with detailed validation and testing setup.

FAQPage Schema
How do I add strict type hints and validation to a Python 3.11+ project?

Add strict type hints to Python 3.11+ projects by applying type annotations directly in your code and enforcing correctness through mypy validation. This ensures robust applications with structured error handling and proper data validation.

What's the best way to set up testing for async Python code?

Set up testing for async Python code by using pytest to validate concurrent I/O-bound operations. This provides comprehensive support for modern async/await patterns, ensuring your type-safe applications handle high concurrency and error scenarios correctly.

Does mypy work with async Python 3.11+ applications?

Yes, mypy works with async Python 3.11+ applications to enforce type safety and code correctness. It validates type annotations within modern async/await patterns, ensuring efficient concurrent code is properly type-checked before production.

Can I use black and ruff together for Python formatting and linting?

Yes, you can use black and ruff together within a modern Python development workflow. Black handles code formatting while ruff manages linting, combining with mypy and pytest to ensure professional code structure and correctness.

How do I build a type-safe async API client with proper error handling?

Build a type-safe async API client by combining strict type annotations, async/await patterns, and structured error handling. Validate the implementation using mypy for type correctness and pytest to test high concurrency and error scenarios comprehensively.

Why does my Python project need structured error handling for async code?

Structured error handling is needed for async Python code to manage concurrent I/O-bound operations safely. It ensures robust applications can handle high concurrency and complex error scenarios without failing unpredictably in production environments.
