I wrote the below code

    def wrapper(self, other):
        msg = 'cannot    compare    a    TimedeltaIndex    with    type    {0}'
        func = getattr(super(TimedeltaIndex, self), opname)
        if (_is_convertible_to_td(other) or (other is NaT)):
            try:
                other = _to_m8(other)
            except ValueError:
                raise TypeError(msg.format(type(other)))
            result = func(other)
            if isna(other):
                result.fill(nat_result)
        else:
            if (not is_list_like(other)):
                raise TypeError(msg.format(type(other)))
            other = TimedeltaIndex(other).values
            result = func(other)
            result = _values_from_object(result)
            if isinstance(other, Index):
                o_mask = (other.values.view('i8') == iNaT)
            else:
                o_mask = (other.view('i8') == iNaT)
            if o_mask.any():
                result[o_mask] = nat_result
        if self.hasnans:
            result[self._isnan] = nat_result
        if is_bool_dtype(result):
            return result
        return Index(result)
    return wrapper

What's a good function header?
 Give me a Python code to compare    a    TimedeltaIndex    with    type    {0}'?

#Here is Python code to compare    a    TimedeltaIndex    with    type    {0}'
