This is the expected behavior. asyncio.ensure_future() returns not a future but a task for your case. Task cancellation requires at least one context switch to finish the task. P.S. I suggest replacing `asyncio.ensure_future()` with `asyncio.create_task()` to avoid confusion. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue37202> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
