I wrote the below code

    input = numpy.asarray(input)
    def derivative2(input, axis, output, mode, cval, sigma, **kwargs):
        order = ([0] * input.ndim)
        order[axis] = 2
        return gaussian_filter(input, sigma, order, output, mode, cval, **kwargs)
    return generic_laplace(input, derivative2, output, mode, cval, extra_arguments=(sigma,), extra_keywords=kwargs)

What's a good function header?
 Here's a good function header?
