What is UV? An fast python package manager and project manager (Written in Rust) replaces pip, pyvenv, virtualenv etc. Runs scripts Installs and Manages Python versions Installation UV can be installed using any one of the package managers (homebrew, pacman etc) Commands Initializing a project uv init <project_name> The above command creates a folder named <project_name>. Inside the project name there is a complete project directory including the virtual environment. UV expects you to follow this project structure. Project Structure: . ├── .venv │ ├── bin │ ├── lib │ └── pyvenv.cfg ├── .python-version ├── README.md ├── main.py ├── pyproject.toml └── uv.lock pyproject.toml This file contains the metadata about the project in question, that can either be added manually by editing this file or by running certain commands.
