:mod:`lab12_exceptions` --- Exceptions
======================================

 Open a non-existent file with open() and catch the resulting exception.

 In the interrupt handler for the IOError, print "IOError: Damn the Torpedoes!" then go into an infinite loop sleeping 1 second at a time.  You must get out with Ctrl-C. Catch the Ctrl-C and in the finally clause print "Carry On!"
