Actually as I tried to say, the dict methods (keys() etc.) DON'T return iterators. They return "views" which are iterable. Anyway, I also tried to imply that it matters if the number of list items would ever be huge. It seems that is indeed possible (even if not likely) so I think iterators are useful. > I am quite happy to be rid of > the 'iter' prefix on the latter. This is aside from itertools.

Agreed, ideally you don't need to know or it'll be obvious from the name without an explicit 'list' or 'iter'. -- --Guido van Rossum (python.org/~guido) _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
