# Python

Use this skill for idiomatic Python guidance across language patterns, concurrency, testing, and type safety.

## When to Use

- Writing or reviewing Python code.
- Choosing between async/await, threading, or synchronous execution.
- Writing tests, handling type annotations, or profiling a hot path.

## Core Pattern

1. Prefer explicit over implicit: write readable code, avoid surprise imports, and document public APIs.
2. Use `asyncio` for I/O-bound concurrency; use `concurrent.futures` or multiprocessing for CPU-bound work.
3. Structure tests with `pytest`, fixtures for shared state, and parametrization for data-driven cases.
4. Add type hints where they clarify contracts; run `mypy` or a type checker in CI.
5. Profile before optimizing; `cProfile` and `line_profiler` identify real bottlenecks.

## Common Mistakes

- Mixing `async` and sync I/O in the same loop. → Await async libraries or run blocking calls in executors.
- Overusing mocks and testing implementation instead of behavior. → Mock boundaries, not internals.
- Ignoring type checker errors. → Treat `mypy` failures like test failures.

Load `references/operational-guidance.md` for deeper coverage of asyncio, pytest, and typing patterns.
