OK thanks, Benjamin,
you are correct sys.maxsize is 2\*63-1 on it. �

I was under the impression that Python was using int\_64\_t for the implementation of Win64 based integers. �Most probably because I've sen discussion on Python 64 bits and those post were most probably were in the scope of some Unix-type platform.

Python int's are platform longs, you get the maxsize of a 32-bit int.
Check sys.maxsize for comparison.
