Python实现ping多个IP地址并返回结果

xlxl

场景：工作中经常会遇到ping内网的多个IP地址，看看能不能ping通，或者在局域网内做ping探测，于是写了这个；


import os
import sys

iplist1 = ['Ping Error']
iplist2 = ['Ping Success']
ipprefix = '10.225.49.'
for i in range(69,72):
        ip = ipprefix + str(i)
        print('@@~~~Start to check %s ~~~@@' %ip)
        PING = os.system('ping -c 2 -i 1 %s' %ip)
        if PING:
                print('@@ping error,the %s not reachable' %ip)
                iplist1.append(ip)
        else:
                print('@@Ping success')
                iplist2.append(ip)
print(iplist1)
print(iplist2)


问题：
我这里把PING的结果打印出来过，发现能ping成功的话，PING的返回结果是0，如果ping不成功，返回的是pipe2, 256这样的一个数字，我虽然基于ping的结果来做一个if判断，但我并不知道原因；
求大神赐教
