HomeBackend DevelopmentPython TutorialPython定时执行之Timer用法示例

本文实例讲述了Python定时执行之Timer用法。分享给大家供大家参考。具体分析如下:

java中Timer的作用亦是如此。python中的线程提供了java线程功能的子集。

#!/usr/bin/env python 
from threading import Timer 
import time 
timer_interval=1 
def delayrun(): 
  print 'running' 
t=Timer(timer_interval,delayrun) 
t.start() 
while True: 
  time.sleep(0.1) 
  print 'main running' 

t是一个Timer对象。【估计内部是使用一个线程】delay一秒钟之后执行delayrun函数。

其中time.sleep函数是用来让主线程暂停一点时间再继续执行。

希望本文所述对大家的Python程序设计有所帮助。
