Return the value for key if key is in the dictionary, else default. If default is not given, it defaults to None, so that this method never raises a KeyError.

I think that's supposed to mean that it won't raise KeyError as a result of the key not being in the dictionary. The actual behaviour is correct, IMO, because it avoids masking bugs, so this could probably be worded better.
