Python Sleep休眠函数

#!/usr/bin/env python

import os import time

def fun(name):     write_name="command %s failed!\n" % name     print write_name     f = open('/tmp/cs.log','a')     f.write(write_name)     f.close()

def tary(name):     print "the command is %s" % name     command_id = os.system(name)     while command_id != 0:         fun(name)         time.sleep(10)         command_id = os.system(name)

time.sleep(5)

tary("reboot")

Python 编程中使用 time 模块可以让程序休眠

具体方法是time.sleep(秒数)，其中“秒数”以秒为单位，可以是小数，0.1秒则代表休眠100毫秒。

# 例1：循环输出休眠1秒 import time i = 1 while i <= 3:     print i # 输出i     i += 1     time.sleep(1) # 休眠1秒 # 例1：循环输出休眠100毫秒 import time i = 1 while i <= 3:     print i # 输出i     i += 1     time.sleep(0.1) # 休眠0.1秒
