See also a meta-issue issue29833. If use OverflowError as a sign of infinite iterator in __length_hint__, this should be documented as a legitimate use case for OverflowError. itertools.repeat.__length_hint__() and reversed.__length_hint__() currently raise a TypeError for infinite iterator. reversed.__length_hint__() returns NotImplemented (which raises a TypeError when convert to a C integer). Both TypeError and NotImplemented are handled by the consumer of __length_hint__: in PyObject_LengthHint(). An OverflowError is treated as error. ---------- nosy: +serhiy.storchaka _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue33939> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
