Set up a new Python project using uv for package management, pyproject.toml for configuration, src-layout for structure, and pytest for testing. This enforces type hints and modern tooling like ruff and mypy.

Migrate an existing Python codebase by adopting pyproject.toml, enforcing type hints, and integrating uv as the package manager. Transition to src-layout and pytest-based testing to align with modern development practices.

Type hints and pyproject.toml are required for modern Python 3.9+ projects. This ensures code quality, enables mypy static analysis, and centralizes packaging configuration, logging, and CI/CD settings.

uv is the recommended package manager for Python packaging. It standardizes project workflows alongside pyproject.toml, providing faster dependency resolution and consistent environment management across teams.

pytest fits into modern Python CI/CD workflows as the standard testing framework. It validates code quality alongside type hints and ruff checks, ensuring maintainable production-ready Python applications.

FastAPI and Django work with the src-layout packaging pattern. This structure separates package code from tests, improving import handling and packaging reliability across framework choices.
