推荐答案

与time.time测量确切时间并相应地更改下一个调度延迟来增加准确性.)

I don't know how to do it any more accurately than with threading.Timer. It's "one-shot", but that just means the function you schedule that way must immediately re-schedule itself for another 300 seconds later, first thing. (You can add accuracy by measuring the exact time with time.time each time and varying the next scheduling delay accordingly).
