本文实例讲述了Python实现定时执行任务的三种方式。分享给大家供大家参考，具体如下：

#!/user/bin/env python# @Time :2018/6/7 16:31# @Author :PGIDYSQ#@File :PerformTaskTimer.py#定时执行任务命令import time,os,schedschedule = sched.scheduler(time.time,time.sleep)def perform_command(cmd,inc): os.system(cmd) print('task')def timming_exe(cmd,inc=60): schedule.enter(inc,0,perform_command,(cmd,inc)) schedule.run()print('show time after 2 seconds:')timming_exe('echo %time%',2) |
2.周期性执行任务

3.循环执行命令

希望本文所述对大家Python程序设计有所帮助。
