Don't do that. Dunder ("Double UNDERscore") methods like __iter__ should only be called by the Python interpreter, not by the programmer. The right way to create an iterator is to call the built-in function iter: b = iter(a) The iter() function may call a.__iter__ (technically, it calls type(a).__iter__ instead) but it may also do other things, which you miss out on if you call __iter__ directly. -- Steve “Cheer up,” they said, “things could be worse.” So I cheered up, and sure enough, things got worse. -- https://mail.python.org/mailman/listinfo/python-list
