本文实例讲述了Python测试网络连通性。分享给大家供大家参考，具体如下：
Python代码
#!/usr/bin/python
# -*- coding:GBK -*-
“””Document: network script, keep network always working, using python3″””
import os
import time
PING_RESULT = 0
NETWORK_RESULT = 0
def DisableNetwork():
”’ disable network card ”’
result = os.system(u”netsh interface set interface 以太网 disable”)
if result == 1:
print(“disable network card failed”)
else:
print(“disable network card successfully”)
def ping():
”’ ping 主备网络 ”’
result = os.system(u”ping 180.97.33.108″)
#result = os.system(u”ping www.baidu.com -n 3″)
if result == 0:
print(“A网正常”)
else:
print(“网络故障”)
return result
if __name__ == ‘__main__’:
while True:
PING_RESULT = ping()
if PING_RESULT == 0:
time.sleep(20)
else:
DisableNetwork()
time.sleep(10)
运行结果：
注：原文为utf-8编码，这里小编测试时发现返回结果会出现乱码，故改为GBK编码。
希望本文所述对大家Python程序设计有所帮助。
