This one works both ways.  32-bit compiled python doesn't run on a 64-bit system because the Python interpreter at /usr/bin/python is 64-bit, and can't load the 32-bit compiled code.

It works fine if you're running from source, because then the interpreter is compiling for the local machine.

For awhile, you had to remove your 64 bit Firefox, and install the 32 bit one, because Flash only ran in 32 bit more. ISTR similar things with 64 bit Java not working either, altho I believe that both seem to be fixed nowadays.
