Generators. But nice catch, thank you! Iterators are *any* object which obeys the iterator protocol, that is, have a next() method and an __iter__() method which behave in the expected way. Iterators are a duck-type. Generators, whether created from a generator expression or a generator function, are an actual type. >>> type(x for x in (1,2)) <class 'generator'> -- Steven -- http://mail.python.org/mailman/listinfo/python-list
