import numpy as np
nums1 = np.ones((2,2,3))
nums2 = 3*np.ones((2,2))
print("Original array:")
print(nums1)
new_array = nums1 * nums2[:,:,None]
print("\nNew array:")
print(new_array)

Sample Output:

Original array:
[[[1. 1. 1.]
  [1. 1. 1.]]

 [[1. 1. 1.]
  [1. 1. 1.]]]

New array:
[[[3. 3. 3.]
  [3. 3. 3.]]

 [[3. 3. 3.]
  [3. 3. 3.]]]
