To be a trifle more explicit, turn:

       ...
       if __name__ == '__main__':
          main()

into:
       ...
       if __name__ == '__main__':
          try:
              main()
          except Exception, why:
              print 'Failed:', why
              import sys, traceback
              traceback.print_tb(sys.exc_info()[2])
          raw_input('Leaving: ')

Note that building your script like this also allows you to
open the interpretter, and type:
     import mymodule
     mymodule.main()
in order to examine how it runs.
