I'm afraid that your question is *far* too advanced for this mailing 
list, which is for beginners. I suggest that you ask your question on 
the main Python list:

    https://mail.python.org/mailman/listinfo/python-list

also available on Usenet at comp.lang.python. If you don't get a 
response there, then you may ask the core Python developers on the 
Python-Dev mailing list:
