numpy add arrays together code example

Example 1: numpy merge arrays

>>> a = np.array([[1, 2], [3, 4]])
>>> b = np.array([[5, 6]])
>>> np.concatenate((a, b), axis=0)
array([[1, 2],
       [3, 4],
       [5, 6]])
>>> np.concatenate((a, b.T), axis=1)
array([[1, 2, 5],
       [3, 4, 6]])

Example 2: 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
