> All iterators are always true, More generally, all objects are true by default. The only false objects in Python are None; container-like objects with a __len__ that returns zero; and number-like objects with a __nonzero__ method that returns False. Guido decided that iterators should not be treated like containers and should not have a __len__ method.
