Python利用WMI实现ping命令的例子

import wmic = 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'

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;};
