Xiang Zhang added the comment: In Py3.6, it raises error:
>>> next((pool.imap(str, gen()))) Traceback (most recent call last): File "/opt/lib/python3.7/multiprocessing/pool.py", line 684, in next item = self._items.popleft() IndexError: pop from an empty deque During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/opt/lib/python3.7/multiprocessing/pool.py", line 690, in next item = self._items.popleft() IndexError: pop from an empty deque During handling of the above exception, another exception occurred: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/opt/lib/python3.7/multiprocessing/pool.py", line 693, in next raise StopIteration StopIteration But this doesn't looks good. I think it should raise TypeError. It can be fixed in #28699. ---------- nosy: +xiang.zhang _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue28696> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
