import numpy as np

arr = np.array([1, 2, 3, 4]) #Original array
x = arr.view()               #View array 
print(arr) #Original array
print(x)   #View Array

arr[0] = 9 #changing the original array

print(arr)
print(x) #by changing original array view array will change

x[0] = 7 #changing the view array

print(arr) #by changing view array original array will change
print(x)

Output-

[1 2 3 4]
[1 2 3 4]
[9 2 3 4]
[9 2 3 4]
