@Ko496-glitch I noticed you working in this area and wanted to draw your attention to this PR #2361 I would be interested in how you are building and encountered the python 3.13 issue and any review comments on the PR. That PR also handles the issue Issue #2358

@gmarzot for this issue i just went through the python directory in the codebase and checked for the most relevant file, good amount of info was already presented as this issue was also handled back in june in pr #42034. The change also seems good to the issuer. let me know if you want any other info on this PR.

I think something like this below is clearer and more direct:

 private:
  static bool isPyFinalizing() noexcept {
#if PY_VERSION_HEX <= 0x03070000     // unsupported anyway - can remove
    return false;
#elif PY_VERSION_HEX >= 0x030D0000  // Python 3.13+
    return Py_IsFinalizing();
#else
    return _Py_IsFinalizing();
#endif
  }

I think the PR I have here includes this solution and addresses a number of other issues getting the python bindings working so I would recommend that PR to the maintainers
