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:

Create the directory for the project, navigate there, and initialize the project with uv init, e.g.:

mkdir my-project
cd my-project
uv init

uv will automatically create a venv and a uv.lock file when we run a uv command now, so run something like uv run main.py to create the venv.
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

You can check the version of your project with uv version

And you can bump versions with:

uv version --bump minor

where we can use major, minor, patch, etc. to update the version
