I took a look. Much better. :-)
Just one further question: is there any reason why you have the code
inside the generated module to raise an error if the generated number
does not match when you are already performing that check after you
import the module successfully? I think you can quite safely remove
that code. In other words, all you want in the generated code is
__codegen_version__ = 42
Then in the importing code
module = __import__()
if module.__codegen_version__ != comtypes.tools.codegenerator.version:
raise ImportError("version mismatch")
Or am I missing something here? Please be gentle if I am. :-)
