Tools for installing, managing, and resolving Python packages and virtual environments.
Package management tools are the foundation of any Python project — they control how dependencies are installed, isolated, and reproduced across machines. From the original pip installer to modern all-in-one managers like uv, these tools handle dependency resolution, virtual environment creation, and lockfile generation to ensure consistent builds in development, CI, and production.

Choose pip when you need maximum compatibility and are working in environments that already use it. Choose virtualenv or venv when you need lightweight isolated environments without additional tooling. Choose uv when speed matters — it is 10–100x faster than pip, replaces virtualenv, and manages Python versions too, making it the best default for new projects.
