Example 1: numpy append number to array
import numpy as np
a = np.array([1, 2, 3])
newArray = np.append(a, [10, 11, 12])
Example 2: append value to numpy array
x = np.random.randint(2, size=10)
x = np.append(x, 2)
Example 3: np array append
>>> import numpy as np
>>> np.append([[0, 1, 2], [3, 4, 5]],[[6, 7, 8]], axis=0)
array([[0, 1, 2],
[3, 4, 5],
[6, 7, 8]])
Example 4: add item to numpy array python
>>> np.append([1, 2, 3], [[4, 5, 6], [7, 8, 9]])
array([1, 2, 3, ..., 7, 8, 9])
Example 5: numpy python add array
x1 = [1, 2]
x2 = [1, 2]
print(np.add(x1, x2))
# [2, 4]
