Someone else pointed out that there might be better data structures. If performance was not an issue one approach would be illustrated by the following: >>> Q=set(['A','a']) >>> list(set(x.upper() for x in Q)) ['A'] This has the benefit that it does not assume all the elements of the set have the same value of the given attribute. Again not very efficient: >>> list(Q)[0] 'A' I'm guessing this would be quicker >>> iter(Q).next() 'A' -- http://mail.python.org/mailman/listinfo/python-list
