Installs Python packages, creates virtual environments, locks dependencies and manages Python versions with one fast command-line tool that replaces pip, pip-tools, pipx, poetry, pyenv and virtualenv. Use when a user asks to set up a Python project, add or upgrade a dependency, create a lockfile, migrate from requirements.txt, run a script with inline dependencies, install a Python version, run a tool with uvx, or speed up installs in CI and Docker.
