Quick reference for Python code quality tools: ruff (linting & formatting), ty (type checking).
Configures Ruff for linting and formatting, mypy or pyright for type checking, pre-commit hooks, lint rule sets, and modern Python typing patterns like PEP 695.
Sets up Python code quality toolchain with ruff linting/formatting, mypy type checking, complexity gating, dead code detection, pre-commit hooks, pyproject.toml config, and Makefile targets.
Lints Python code with ruff: fast checks, rule selection, auto-fixing, output formats, configuration. Use for code quality, bug detection, standards enforcement.
