That's probably because str and unicode don't do their own iteration, but rely on the fallback implementation. In which case it's perfectly correct for them not to have an __iter__ method. If you want to test whether something is iterable, it's not enough to test for __iter__ -- you also need to test for __len__ and __getitem__ as an alternative. Which means it might make sense to have an iterable() function which does that. -- Greg _______________________________________________ Python-3000 mailing list Python-3000@python.org http://mail.python.org/mailman/listinfo/python-3000 Unsubscribe: http://mail.python.org/mailman/options/python-3000/archive%40mail-archive.com
