>>> and the test for an iterator is: >>> >>> obj is iter(obj)
Is that a hard and fast rule? I know it’s the vast majority of cases, but I imagine you could make an object that behaved exactly like an iterator, but returned some proxy object rather that itself. Not sure why one would do that, but it should be possible. - CHB _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
