How to figure out if the platform is 32bit or 64bit?

[Ken Hartling]

Thanks .. but I want to find out if the system is "running on 64bit" even
when the interpreter is a
32-bit build executable ("what python was built on").
platform.architecture() and platform() in general seems to only be looking
at the build executable and what it was built for on windows (sorry, I don't
have a unix box available at the moment).  platform.architecture() returns
32bit when on a windows 64bit box.

Another recommendation was:
import sys
hex(sys.maxint)
x = sys.maxint
n = 1
while x:
    n += 1
    x >>= 1

print n

Unfortunately this too appears to be looking at the build executable ... on
Windows 64 it returns '32'.

Thanks for the suggestions, hopefully we'll come up with a winner.
