You could do this maybe:

  import sys

  def excepthook(exc_type, exc_value, tb):
    import modules_needed_to_notify_exception
    ...

  sys.excepthook = excepthook

  import modules_needed_by_script
  ...
having tested this more, I was worried about a recursive call to exception should an exception be raised inside the function but luckily python deals and give you a double traceback.

batteries included indeed.

Thanks again

I see that the exceptionhook is handed 3 things, the name of the error, the explanation,  and the traceback object.

Does anybody know how I can get the linenumber of the error the way it does normally, since this is very useful info when debugging.
I think I need the traceback module but I can't see how to extract the extra info from the traceback object passed to excepthook.
