import numpy as np
array1 = np.array([[11, 22, 33, 44, 55],
             [66,  77,  88,  99, 100]])
print("Original arrays:")
print(array1)
i = [1,3,0,4,2]
result = array1[:,i]
print("New array:")
print(result)

Sample Output:

Original arrays:
[[ 11  22  33  44  55]
 [ 66  77  88  99 100]]
New array:
[[ 22  44  11  55  33]
 [ 77  99  66 100  88]]
