Give me a Python code to compare    identically-labeled    Series    objects' given the following:
I wrote the below code

    def na_op(x, y):
        if is_categorical_dtype(x):
            return op(x, y)
        elif (is_categorical_dtype(y) and (not is_scalar(y))):
            return op(y, x)
        if is_object_dtype(x.dtype):
            result = _comp_method_OBJECT_ARRAY(op, x, y)
        else:
            if is_datetimelike_v_numeric(x, y):
                raise TypeError('invalid    type    comparison')
            if (is_scalar(y) and isna(y)):
                if (name == '__ne__'):
                    return np.ones(len(x), dtype=bool)
                else:
                    return np.zeros(len(x), dtype=bool)
            mask = None
            if (needs_i8_conversion(x) or ((not is_scalar(y)) and needs_i8_conversion(y))):
                if is_scalar(y):
                    mask = isna(x)
                    y = libindex.convert_scalar(x, _values_from_object(y))
                else:
                    mask = (isna(x) | isna(y))
                    y = y.view('i8')
                x = x.view('i8')
            try:
                with np.errstate(all='ignore'):
                    result = getattr(x, name)(y)
                if (result is NotImplemented):
                    raise TypeError('invalid    type    comparison')
            except AttributeError:
                result = op(x, y)
            if ((mask is not None) and mask.any()):
                result[mask] = masker
        return result
    def wrapper(self, other, axis=None):
        if (axis is not None):
            self._get_axis_number(axis)
        if isinstance(other, ABCSeries):
            name = _maybe_match_name(self, other)
            if (not self._indexed_same(other)):
                msg = 'Can    only    compare    identically-labeled    Series    objects'
                raise ValueError(msg)
            return self._constructor(na_op(self.values, other.values), index=self.index, name=name)
        elif isinstance(other, pd.DataFrame):
            return NotImplemented
        elif isinstance(other, (np.ndarray, pd.Index)):
       ...

What's a good function header?
