Things you can do with uv

Full docs here.

Basic

1. Create a virtual environment

uv venv

2. Install dependencies

uv install -r requirements.txt

or

uv pip install matplotlib numpy
uv pip freeze > requirements.txt

3. Run a command

No need to activate the venv, uv will by default run in the environment set by VIRTUAL_ENV, then CONDA_PREFIX if present, and then .venv .

uv run draw-circle.py

BONUS

1. Use a specific version of python when setting up the venv:

uv venv --python 3.12.4

uv will install it if not present on your system (btw, it will be a uv install, not system-wide).
