I wrote the below code

    attrs = frozenset(attrs)
    msg = "'{name}[{attr!r}]'    is    deprecated,    please    use    '{name}.{attr}'    instead"
    def __getitem__(self, key):
        '``__getitem__``    is    deprecated,    please    use    attribute    access    instead.\n                                '
        warn(msg.format(name=name, attr=key), DeprecationWarning, stacklevel=2)
        if (key in attrs):
            return self.__dict__[key]
        raise KeyError(key)
    return __getitem__

What's a good function header?
