http://stackoverflow.com/questions/68630/are-tuples-more-efficient-than-lists-in-python http://jtauber.com/blog/2006/04/15/python_tuples_are_not_just_constant_lists/ Tuples are not constant lists -- this is a common misconception. Lists are intended to be homogeneous sequences, while tuples are hetereogeneous data structures. Tauber's point about tuples being structures named by index, seemed correct in light of "namedtuple" in collections (since Python 2.6) Also, as Noufal mentioned, tuples are hashable, so you can use them as keys in a dict. -- Roshan Mathews http://teamtalk.im _______________________________________________ BangPypers mailing list BangPypers@python.org http://mail.python.org/mailman/listinfo/bangpypers
