WMI是Windows系统的一大利器，Python的win32api库提供了对WMI的支持，安装win32api即可使用 WMI。
本例通过WMI的WQL实现ping命令。
import wmi
c = wmi.WMI()
wql = "SELECT StatusCode FROM Win32_PingStatus WHERE Address = '127.0.0.1'"
for i in c.query(wql):
if i.StatusCode:
print 'offline'
else:
print 'online'
c.query(wql)的结构如下，其中StatusCode为0表示能够ping通，大于0表示ping不通
instance of Win32_PingStatus
{
Address = "127.0.0.1";
BufferSize = 32;
NoFragmentation = FALSE;
RecordRoute = 0;
ResolveAddressNames = FALSE;
SourceRoute = "";
SourceRouteType = 0;
StatusCode = 0;
Timeout = 1000;
TimestampRoute = 0;
TimeToLive = 128;
TypeofService = 128;
};
