[Fedora-suds-list] Checking for the existence of elements in a response

Hey, a big thanks to Jeff for helping me figure out how to use the Doctor :) It was much appreciated. I currently have a bit of a problem, though. I have looked through the documentation and can't seem to find out what object/ client.service/ returns. This is my code: result = client.service.DoSomethingIncrediblyInteresting(WithADiscoStick) info = result.*FirstField*.SomeTable.SomeData.somethingorother.DooDah The thing is that sometimes *FirstField *doesnt exist which causes my Python program to quit rather angrily. Is there a check I can do on result, FirstField, and so on, to check of the children I'm about to grab info from actually exist? Thanks, Rob.
