Your version needs Python. uv needs needs only uv, as it can manage python installation by itself.

It's also a lot easier to install uv than to manage Python installations (there's a reason pyenv and the like exist).

That's fair point. Its maybe different use case. For me main goal was to be able to run project scripts on macos and Linux ootb, and both have some python 3 version already available ootb.

But probably if you need specific python version it isn't best way
