Python实现ping指定IP的示例

import os

import sys

iplist = list()

ip = '192.168.1.11'

# ip = '172.24.186.191'

ip = 'www.baidu.com'

backinfo = os.system('ping -c 1 -w 1 %s'%ip) # 实现pingIP地址的功能，-c1指发送报文一次，-w1指等待1秒

print 'backinfo'

print backinfo

print type(backinfo)

if backinfo:

 print 'no'

else:

 iplist.append(ip)

print iplist
