If anyone else is also barely aware and confused by the similar names, PyPI is the Python Package Index, which is up and maintained. PyPy is "A fast, compliant alternative implementation of Python." which doesn't have enough devs to release a version for 3.12[0].

Thanks for the clarification. On top of that, being an issue in the 'uv' GitHub repo (uv installs packages from PyPi) made my brain easily cross the letters.

and mypy is "an optional static type checker for Python" [0]

Given that both pypy (through RPython) and mypy deal with static type checks in some sense, I kept confusing the two projects until recently.

Also, I just learnt (from another comment in this post) about mypyc [1], which seems to complete the circle somehow in my mind.

The short summary of it being that these people are beyond terrible at giving names to things.
