Ah, good.  Exactly what the useful functions in the
'traceback' module are intended for, if I understand
your meaning...

If doing "traceback.print_exc()" is printing the
information you want (in a traceback that has much
more than what you say you want), then you can use
the other functions in that module, and methods in
the 'traceback' objects themselves (the third item
in the tuple returned by sys.exc_info()), will
give you all you could ever want...

Google can help you find examples of usage as well,
in the archives for this group.
