# Python
|
|
|
|
- Follow PEP 8: snake_case for functions/variables, PascalCase for classes, UPPER_CASE for constants
|
|
- Use type hints on all function signatures; validate with `mypy` or `pyright`
|
|
- Use `pydantic` for data validation and serialization
|
|
- Import order: stdlib -> third-party -> local; use absolute imports
|
|
- Use context managers (`with`) for resource management
|
|
- Catch specific exceptions, never bare `except:`; use custom exception classes
|
|
- Use `async`/`await` with `asyncio` for I/O-bound concurrency
|
|
- Use `pytest` for testing (not `unittest`); fixtures for setup/teardown
|
|
- Use virtual environments (`venv` or `poetry`); pin dependencies
|
|
- Format with `black`; lint with `ruff` or `flake8`
