> In Python 3.11, time.sleep() is now always implemented with a > waitable timer. A regular waitable timer in Windows becomes signaled with the same resolution as Sleep(). It's based on the current interrupt timer period, which can be lowered to 1 ms via timeBeginPeriod(). Compared to Sleep() it's more flexible in terms of periodic waits, WaitForMultipleObjects(), or MsgWaitForMultipleObjects() -- not that time.sleep() needs this flexibility. That said, using a waitable timer leaves the door open for improvement in future versions of Python. In particular, it's possible to get higher resolution in newer versions of Windows 10 and Windows 11 with CreateWaitableTimerExW() and the undocumented flag CREATE_WAITABLE_TIMER_HIGH_RESOLUTION (2). ---------- nosy: +eryksun _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue21302> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
