import numpy as np
my_array = np.arange(12).reshape(3, 4)
print("Original array:")
print(my_array)
my_array[:,[0, 1]] = my_array[:,[1, 0]]
print("\nAfter swapping arrays:")
print(my_array)

Sample Output:

Original array:
[[ 0  1  2  3]
 [ 4  5  6  7]
 [ 8  9 10 11]]

After swapping arrays:
[[ 1  0  2  3]
 [ 5  4  6  7]
 [ 9  8 10 11]]
