python实现ping操作并接收返回信息

这段python代码调用windows下的ping命令，通过subprocess在其子进程里面实现，由于windows下的ping和linux下的ping返回的消息不太一样，所以这段python代码要想在linux下运行，需要修改一下正则匹配

import subprocess   
import re
p = subprocess.Popen(["ping.exe", 'google.com'],
                                         stdin = subprocess.PIPE,
                                         stdout = subprocess.PIPE,
                                         stderr = subprocess.PIPE,
                                         shell = True)   

out = p.stdout.read()                                    
regex = re.compile("Minimum = (\d+)ms, Maximum = (\d+)ms, Average = (\d+)ms", re.IGNORECASE)
print regex.findall(out)
