python-uv

To set up a new Python project with uv, run uv init to generate the pyproject.toml file and configure the project structure. This command initializes your project directory and optionally syncs the environment.

The best way to manage Python dependencies is using uv add to specify packages and group-based dependencies. This separates dev and production requirements, while uv lock ensures reproducible environments across teams.

uv lock ensures reproducible Python environments by generating a uv.lock file that pins exact dependency versions. Running uv sync uses this lockfile to recreate identical virtual environments across different machines.

Yes, you can use uv for virtual environment and lockfile management in existing projects. The uv sync command reads your pyproject.toml and uv.lock to install dependencies and configure the environment consistently.

You should use uv for dependency handling because it integrates project initialization, pyproject.toml configuration, and uv.lock generation into a single workflow. It enforces environment consistency and reproducible builds across teams.
