I wrote the below code

    def maptuple(k):
        if isinstance(k, tuple):
            if (len(k) == 2):
                return k
            elif (len(k) == 1):
                return (k[0], _create_invoker(obj, (prefix + k[0])))
            else:
                raise ValueError()
        else:
            return (k, _create_invoker(obj, (prefix + k)))
    return dict([maptuple(k) for k in keys])

What's a good function header?
