I've written a Python program that generates tests and answer keys from

random values on 32-bit and 64-bit systems.

I think the problem is that hash(<str>) generates different values on
the 32 and 64 bit systems. I found that by using 

random.seed(hash(<str>) & 0xffffffff)

I can get the same results.  Is there a better way? Is my way "safe" and
