TypeError: _append_dispatcher() missing 1 required positional argument: 'values'

Answer 1

You have only given 1 parameter (which is the array you want to add) but not given the 2nd parameter (which is what array to add to?). This should work for you:

import numpy as np

a = np.array([1,2,3],  [4,5,6])

b = np.array([7,8,9])

c = np.append(a, b)

print(c)
