get python bit version as in (32 or 64)

[Vincent Davis]

How do I get the bit version of the installed python. In my case, osx
python2.7 binary installed. I know it runs 64 bt as I can see it in
activity monitor. but how do I ask python?
sys.version
'2.7 (r27:82508, Jul  3 2010, 21:12:11) \n[GCC 4.0.1 (Apple Inc. build 5493)]'
