如何获取y和z之间的每x分钟循环的python代码？

Question

This might be incredibly easy but how do I get python code to loop every x mins between the times y and z?

For example if I wanted my script to run between midnight (00:00) through to 10 pm (22:00) looping every 5 minutes.

Try the sched module in the standard library. Here's an example of calling a function once per second, starting five seconds in the future, and ending ten seconds in the future:

from sched import scheduler
from time import time, sleep

s = scheduler(time, sleep)

def run_periodically(start, end, interval, func):
    event_time = start
    while event_time < end:
        s.enterabs(event_time, 0, func, ())
        event_time += interval
    s.run()

if __name__ == '__main__':

    def say_hello():
        print 'hello'    

    run_periodically(time()+5, time()+10, 1, say_hello)

Alternatively, you can work with threading.Timer , but you need to do a little more work to get it to start at a given time, run every five minutes, and stop at a fixed time.
