May I suggest yet one more alteration: try: ...code... except (KeyboardInterrupt,SystemExit): raise except: ...handler... Not unless you want to run around editing hundreds of modules. To quote someone who shall remain anonymous: The joy of coding Python should be in seeing short, concise, readable classes that express a lot of action in a small amount of clear code -- not in reams of trivial code that bores the reader to death.

How many bare except: clauses that should be bare are there? To my way of thinking, requiring the above construct on top of a bare except: is precisely the kind of wart we wish to encourage in order to discourage bare except: clauses. In any event, it was Guido's idea to add the 

except KeyboardInterrupt:

in the first place; I'm simply adding the logical extension. Perhaps instead of the StandardError idea suggested by others, we should add a new exception called ExitException that inherits from both SystemExit and KeyboardInterrupt.
