It can be useful when you think something might be None or False. Although, I suppose you could always just use 'is None' instead. >>> 1 == True True >>> 1 is True False >>> 0 == False True >>> 0 is False False Granted, the above example is a pretty facetious case; not sure I can come up with a reasonably real world use case.
