glad you found the ramble of use :-)

Your python is a version before set was a built-in type (2.4, I 
believe). So, the iteration_comparison *and* dupe_detector_5 functions 
won't work for you.

2.3 did include the sets module, though.

So, stick

from sets import set

at the top of the code and it ought work.
