Use the resize and reshape method on Numpy array. Data science using Python in Anaconda - Jupyter

import numpy as np

ar1 = np.array([1,2,3,4,5,6,7,8])

ar2 = np.array([1,2,3,4,5,6,7,8])

#It change orignal array

ar2.resize(2,4) 

#It dose not change orignal array

ar1.reshape(2,4)

print("ar1 :-\n", ar1)

print("ar2: -\n", ar2)

Output: -

ar1 :- [1 2 3 4 5 6 7 8] ar2: - [[1 2 3 4] [5 6 7 8]]
