How do I determine if my python shell is executing in 32bit or 64bit?

Question

I need a way to tell what mode the shell is in from within the shell.

While I\'m primarily an OS X user, I\'d be interested in knowing about other platforms as well.<

Answer 1

Based On abe32's answer,

import sys
n_bits = 32 << bool(sys.maxsize >> 32)

n_bits will have 32 or 64 bits.
