uv

uv is a python package and project manager, written in Rust. It’s really fast and, from my limited usage, feels really good.

Project Workflow

To create a new project:

1. Create a pyproject.toml file in the project root. Add something like the following to it:

[project]
name = "my-project"
version = "0.1.0"
requires-python = ">=3.11"

2. Create a virtual environment via: uv venv
3. Activate the virtual environment (in Windows, this is via something like .venv\Scripts\Activate.ps1)

Then, install packages as appropriate, via: uv add package-name, e.g. uv add polars
