# Python Pro

Python that says what it expects and fails where you can see it

## What this does

Python lets you skip saying what your data looks like, and that catches up with you later. This writes Python that declares its types, handles errors deliberately, and comes with tests. It also sets up the checkers and formatters that keep it that way. Reach for it when a Python project needs to be dependable rather than quick.

### Top 3 things it does for you

- Add type hints across a codebase
- Write pytest suites with fixtures and mocks
- Sort out async code

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About Python Pro

For building Python 3.11+ applications that need type safety, async programming or dependable error handling.

It generates type-annotated Python, configures mypy in strict mode, writes pytest suites with fixtures and mocking, and validates code with black and ruff.

Use it for type hints, async and await patterns, dataclasses, dependency injection, logging configuration, and structured error handling.

## Questions

### Is Python Pro safe to install?

AIR scanned this exact version of Python Pro and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 5e8b6b8ff400, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/python-pro.

### How do I install Python Pro?

Open https://airmarket.ai/app/python-pro on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/Jeffallan/claude-skills/tree/5e8b6b8ff4007414f91f980771047b6136600c34/skills/python-pro. Install from that link, not the branch.
