exception handling

[Jp Calderone]

 Is there any way to catch *all* exceptions raised in a 
try/except block *and* get a reference to the exception
that was raised?  I basically just need to print out the
exception, as the interpreter does when an unhandled
exception is raised, but with extra formatting and such.
I've tried the sys.exc_info() function, but it always
seems to return (None, None, None) - even when it is
being called in an except block, where it obviously
*should* have info on an exception.

 Thanks in advance,
  Jp
