[Numpy-discussion] What is the pythonic way to write a function that handles arrays and scalars?

On minor thing that instead of 'ret' there should be 'x'.

With kind regards, -gdg

the best example I found was this one:


def func_for_scalars_or_vectors(x):
    x = np.asarray(x)
    scalar_input = False
    if x.ndim == 0:
        x = x[None]  # Makes x 1D
        scalar_input = True

    # The magic happens here

    if scalar_input:
        return np.squeeze(ret)
    return ret

Is this as good as it gets or do you have other suggestions?
