Python定時調度--多任務同一時間開始跑 scheduler.enterabs

Event Priorities

If more than one event is scheduled for the same time their priority values are used to determine the order they are run.

import schedimport timescheduler = sched.scheduler(time.time, time.sleep)def print_event(name):    print ‘EVENT:‘, time.time(), namenow = time.time()print ‘START:‘, nowscheduler.enterabs(now+2, 2, print_event, (‘first‘,))scheduler.enterabs(now+2, 1, print_event, (‘second‘,))scheduler.run()

 

This example needs to ensure that they are scheduled for the exact same time, so the enterabs() method is used instead of enter(). The first argument to enterabs() is the time to run the event, instead of the amount of time to delay. The second argument is the priority value, smaller number is more prioriable.

$ python sched_priority.pySTART: 1361446608.62EVENT: 1361446610.62 secondEVENT: 1361446610.62 first
