import numpy as np
arr = np.array([[1, 2]])
arr = np.append(arr, [[3, 4]], axis=0)ctrl + cgithub

`import numpy as np` load Numpy module for Python	`np.array` declare Numpy array
`[[1, 2]]` sample 2-dimensional array	`np.append` append values to specified array
`arr` array to append new values to	`[[3, 4]]` new values array to append to `arr` (should have the same dimension count)
`axis=0` axis to add new values along

import numpy as np
a = np.array([[1, 2]])
a = np.append(a, [[3, 4]], axis=0)
print(a)
