Execute all of your "user" or "application" Python code inside your own 
, Python implemented exception handler.  This handler can catch all 
errors, and use the traceback module to print the exception details 
anywhere it likes.

This is the approach taken by Pythonwin and IDLE, to name just a couple 
I am familiar with...
