Small bug fix: in comparison to CreateModule.py this codeline is missing in CreatePyModule.py, so CreatePyModule.py doesn't work,fine without it (tested under Win 7 and Win11)
Static analysis showed some unused variables and imports, and running
the code in Python 3.9 revealed a few invalid escapes (previous versions
of Python silently "fixed" these, so the code change here will not
affect the results).
