Why do you care if a Python int object uses 32 or 64 bits internally? 
Python 2.x will automatically switch to long when needed. The size of 
the Python integer is an internal implementation detail you will not 
notice. Python knows when to use a long instead of an int. Python 3.x 
does not even have a fixed-size integer.

64 bit Python is 64 bit Python, even on Windows. The difference between 
32 bit and 64 bit Python is what you would expect: The size of a C 
pointer is 64 bits, and the virtual address space is much larger (in 
general not 2**63-1 bytes, but some OS dependent value).
