Routes to specialized skills for frameworks and testing. allowed-tools: Read Write Edit Grep Glob Bash --- # Python-Coder Modern Python 3.12+ development patterns. ## Related Skills (Use for Specific Needs) | Skill | Use When | |-------|----------| | `fastapi-coder` | Building FastAPI services | | `django-coder` | Django web applications | | `pytest-coder` | Writing comprehensive tests | | `python-debugger` | Debugging Python code | ## Modern Tooling Quick Reference ### Package Management (uv) ```bash # Project setup uv init my-project uv add fastapi pydantic uv add --dev pytest ruff mypy # Run commands uv run python main.py uv run pytest ``` ### Code Quality (ruff) ```toml # pyproject.toml [tool.ruff] line-length = 100 target-version = "py312" [tool.ruff.lint] select = ["E", "F", "I", "UP", "B"] [tool.ruff.format] quote-style = "double" ``` ### Type Checking (pyright/mypy) ```toml [tool.pyright] pythonVersion = "3.12" typeCheckingMode = "strict" ``` ## Python 3.12+ Patterns ### Pattern Matching ```python match command: case {"action": "create", "item": item}: create(item) case {"action": "delete", "id": int(id)}: delete(id) case _: raise ValueError("Unknown command") ``` ### Modern Async ```python async def fetch_all(urls: list[str]) -> list[dict]: async with aiohttp.ClientSession() as session: tasks = [fetch(session, url) for url in urls] return await asyncio.gather(*tasks) ``` ### Type Hints ```python from typing import TypeVar, Protocol T = TypeVar("T") class Repository(Protocol[T]): def get(self, id: int) -> T | None: ... def save(self, entity: T) -> T: ... ``` ## Behavioral Standards - PEP 8 + ruff formatting - Type hints throughout - Tests with pytest (>90% coverage target) - Prefer stdlib before external deps - Comprehensive error handling with custom exceptions
