pythonTask scheduling

本文实例讲述了python任务调度实现方法。分享给大家供大家参考。具体如下：

方法1:

import sched, time
import os
s = sched.scheduler(time.time, time.sleep)
#scheduler的两个参数用法复杂,可以不做任何更改
def playmusic(x):
  os.system(x)
def jobtodo():
   tmlist = [2011,8,11,22,15,0,0,0,0]
   x1=time.mktime(tmlist)
   x2=time.time()
   y=x1-x2
#计算任务到现在的时间长度
   s.enter(y, 1, playmusic, ('mplayer /home/c.mp3',))
#四个参数分别为：间隔事件、优先级（用于同时间到达的两个事件同时执行时定序）、被调用触发的函数，给他
#的参数（注意：一定要以tuple给如，如果只有一个参数就(xx,)）
   s.run()
   print time.time()
jobtodo()

方法2：

import os
import time
from threading import Timer
def playmusic(x):
  os.system(x)
def jobtodo():
   tmlist = [2011,8,11,22,40,0,0,0,0]
   x1=time.mktime(tmlist)
   x2=time.time()
   y=x1-x2
   Timer(y, playmusic, ('mplayer /home/b.mp3',)).start()
jobtodo()

希望本文所述对大家的Python程序设计有所帮助。
