New submission from Vlad Starostin <drtyrsa@yandex.ru>: The docstring says "This may be None or an instance of EventLoop". But docs explicitly state that get_event_loop "must never return None". The same docstring is also in the example in docs: https://docs.python.org/3.6/library/asyncio-eventloops.html#customizing-the-... I propose changing it to: def get_event_loop(self): """Get the event loop. Returns an instance of EventLoop or raises an exception. """ If the wording is ok, I'll make a PR. ---------- assignee: docs@python components: Documentation, asyncio messages: 323190 nosy: asvetlov, docs@python, drtyrsa, yselivanov priority: normal severity: normal status: open title: Fix the docstring for AbstractEventLoopPolicy.get_event_loop versions: Python 3.6, Python 3.7, Python 3.8 _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue34344> _______________________________________
