STINNER Victor added the comment: Hum, I dislike this change since it's non-obvious what/who is raising the OverflowError. If an object calls a function in __len__() and the function raises OverflowError, should we consider that object is "true"? In temptation to guess, I prefer to not guess but passthrough the exception.
If you want to support bool(range(1<<1000)), we need to get the result of __len__() as a Python object rather than a C Py_ssize_t. Maybe, if __len__() raises an OverflowError: call again the len(), but using the "__len__" method instead of the slot? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue29840> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
