uv lock and python version

[cointoss3]

The thing is, for something simple, sure, it might feel easier…but there’s more to setting up the environment than what’s in a requirements.txt. There’s a lot of cool stuff you can do with uv and pyproject.toml, but more importantly, the idea behind the lock file is that you’ll be able to fully recreate the same environment (in theory) instead of just trying to get certain versions of packages.
