Python Development

Respect the project

Inspect pyproject.toml, uv.lock, requirements files, Python version constraints and repository instructions. Work in a project virtual environment. The App provides Python, uv, Ruff and pytest as a fallback; prefer project-pinned versions when present.

Install and verify

For a uv project, run uv sync --locked and use uv run pytest, uv run ruff check and uv run ruff format --check. For a requirements project, create .venv with uv venv, then uv pip install -r requirements.txt. Avoid modifying the shared interpreter or using system pip.

Tests

Run the relevant tests after changes and report actual failures. Do not replace application dependencies with tools from the App's private development environment. Use uv run so tests import the project's dependencies.
