python – how to concatenate a zero dimensional array in NumPy

    def adder(data, times):
        for i in range(1, times + 1):
            z = np.zeros((len(data), 1), dtype=float)
            data = np.append(data, z, axis=1)
        return data

my_data = adder("my_data", 5)

when I run this code I get the error below

return concatenate((arr, values), axis=axis)
File “<array_function internals>”, line 5, in concatenate
ValueError: zero-dimensional arrays cannot be concatenated

Please how can I fix this ?
