You have to specify the version of the limited API that you want to use.
Each release adds more symbols to the limited API.
So if you compile against 3.10 version it works with 3.10, 3.11, 3.12 etc,
but not with 3.9.

My pycxx project has test code that I use to verify pycxx’s use of python API.
You could check out the source and run my tests to see how things work.
It is on https://sourceforge.net/projects/cxx/
