随机sleep
sleeptime=random.randint(0, 300)
time.sleep(sleeptime)以下为转载Http://hi.baidu.com/liuhelishuang/item/1f8cd8f75bd246dd6325d28c
import os

f.close()

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
