random.choice(...) requires that the object passed to it supports "sequencing". This means it must implement: __getitem__ (which a list does). I don't think there is a way to retrieve a random element from a set without first turning it into a sequence (list) unless the underlying data of a set were exposed. --James -- http://mail.python.org/mailman/listinfo/python-list
