OverflowError covers cases like greater-than-sys.maxsize range instances, where the object itself is conceptually finite, but the length can't be represented as a C integer. This case is different: it's a category error where the question being asked doesn't even make sense for the affected type. However, unlike len(), where a missing __len__() implementation inherently raises TypeError, backwards compatibility requires operator.length_hint() to handle a missing implementation __length_hint__ implementation as equivalent to an implementation that returns a length hint of 0. ---------- _______________________________________ 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
