I intend to transcribe a C ++ program that uses Qt, to Python, since it was time to update it from the old version 3 of Qt. However, when trying to recompile using the new Qt5, I find that half of the code must be rewritten again. Then it occurred to me to rewrite it from scratch in Python, taking advantage of the fact that it is also possible to use Qt with it. The issue is that Python is not only famous for its ease of learning and expressiveness, but also for its slowness of execution, and that is why I would like to accelerate it to the maximum by compiling native executable. I understand that Py2Exe does it very well, but I do not know if it supports third-party libraries, particularly pyQt5. Does anyone know if it is possible to combine Py2Exe with Qt to achieve clear, consistent and fast programs? Thank you very much already.
