No that's not a good idea. When the set/dict documentation says you get the keys in an undetermined order, it doesn't mean the ordering is random. It means there is a fixed ordering controlled by the implementation and not by you. If you want a random sample, use random.sample(). See the docs for the random module. -- http://mail.python.org/mailman/listinfo/python-list
