See especially the notice at the front of the current sets doc which
says "deprecated since 2.6" and the comparison down the end which
explains why the built-in set() and frozenset() are better than the
sets module. Starting now to use the sets module is not a good idea
unless the OP is stuck on using Python 2.3 .
