Have you worked thoroughly through the Python tutorial
<URL:>? You will exercise many
fundamental concepts, including the exception handling system.

You achieve this by one of two methods:

* start with a program that does extermely little, and add as little as
  possible until you have a very small program which demonstrates the
  behaviour. Once you have this, continue below.

* remove apparently-irrelevant parts from the program until the
  behaviour stops occuring; the most recent removal, then, is at least
  related to the behaviour. Add it back in.

Repeat these until you have aprogram which can't have any part of it
removed without losing the behaviour that's confusing you. Once you have
that, post it here with your question.
