Exercise 1

Use np.arange and reshape to create the array

A = [[1 2 3 4]
     [5 6 7 8]]



In [1]:

    
import numpy as np
A = np.arange(1, 9).reshape(2, -1)
print A

Use np.array to create the array

B = [1 2]



In [2]:

    
B = np.array([1, 2])
print B

Use broadcasting to add B to A to create the final array

A + B = [[2  3  4  5]
         [7  8  9 10]

Hint: what shape does B have to be changed to?



In [3]:

    
print A + B.reshape(2, 1)









    



[[ 2  3  4  5]
 [ 7  8  9 10]]
