Note

Since astral has now officially announced the beta of ty, i’d like to share my current setup of amazing and fast tools:

• uv is for managing python dependencies and python itself. Rigorous environment locks included, which you absolutely need. Can also do versioning, building and publishing.
• pixi is for when you need to have conda dependencies. It uses uv under the hood for pypi deps, which is why I try to add everything as a pypi dependency (pixi add --pypi x).
• ruff is a linter. I don’t want to see any of you manually formatting code, inserting spaces and the like. Just use ruff.
• ty (now officially in beta) is a static type checker. It’ll tell you things like when you return or pass the wrong type, which will probably make your code malfunction. You can use it as a full language server, so it’ll also tell you diagnostics, give (non-AI) code completions for known symbols, and show docstrings.

All of these are built in rust and just generally nice to use.

Honorable mention to loguru for being a logger that I actually can remember how to use (from loguru import logger; logger.info('hello')).
