Just test for maxint value:

from sys import maxint
if maxint >33:
print "more than 32 bits" # probably 64
else:
print "32 bits"


Best regards,
Manuel.

If just for Windows I believe you can use the "PROCESSOR_ARCH ITECTURE"
environment variable -- at least on NT-based Windows versions.

Values are x86 (32-bit), IA64 (64-bit) and AMD64 (64-bit).

Here is a "platinfo.p y" module that might help if you need to do this
