import numpy as np 
nums = np.arange(16, dtype='int').reshape(-1, 4)
print("Original array:")
print(nums)
print("\nNew array after swapping first and last rows of the said array:")
new_nums = nums[::-1]
print(new_nums)

Sample Output:

Original array:
[[ 0  1  2  3]
 [ 4  5  6  7]
 [ 8  9 10 11]
 [12 13 14 15]]

New array after swapping first and last rows of the said array:
[[12 13 14 15]
 [ 8  9 10 11]
 [ 4  5  6  7]
 [ 0  1  2  3]]
