how to add data to numpy array code example

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: how to add numpy arrays

added = a+b #elementwise
added_in_the_end = np.concatenate(a,b) #add at the end of the array
#if you want to add in multiple dimentions check the documentation of np.concatenate

Example 4: numpy python add array

x1 = [1, 2]
x2 = [1, 2]
print(np.add(x1, x2))
# [2, 4]
