"Ignoring AttributeError for devices without a group when using evt.DeviceGroups in a transform"

Hi all. I had an event transform set up in zenoss 3.2.0 using the evt.DeviceGroup attribute. I was getting the following errors in event.log (a lot of these over and over):
2011-11-15T11:42:43 WARNING zen.Events Error processing transform/mapping on Event Class /
Problem on line 0: AttributeError: Event instance has no attribute 'DeviceGroups'
if evt.DeviceGroups == '|/GroupName':
This was the transform:
if evt.DeviceGroups == '|/GroupName':
   con = device.findDevice('DeviceDependency')
   if con.getPingStatus() > 0:
       evt.eventState = 2 # suppressed
       evt.severity = 0 # clear
After reading http://stackoverflow.com/questions/610883/how-to-know-if-an-object-has-an-attribute-in-python http://stackoverflow.com/questions/610883/how-to-know-if-an-object-has-an-attribute-in-python and http://stackoverflow.com/questions/574730/python-how-to-ignore-an-exception-and-proceed http://stackoverflow.com/questions/574730/python-how-to-ignore-an-exception-and-proceed I changed the transform to:
try:
   if evt.DeviceGroups == '|/VP':
       con = device.findDevice('Carlsbad VPN Concentrator')
       if con.getPingStatus() > 0:
           evt.eventState = 2 # suppressed
           evt.severity = 0 # clear
except AttributeError:
   sys.exc_clear()
Does this look like a better transform? Does anyone have a better recommendation?
