Program to multiply two matrices (vectorized implementation)

Program to multiply two matrices (vectorized implementation)
import numpy as np
take a 3x3 matrix
A = [[12, 7, 3],
[4, 5, 6],
[7, 8, 9]]

take a 3x4 matrix
B = [[5, 8, 1, 2],
[6, 7, 3, 0],
[4, 5, 9, 1]]

result will be 3x4

result= [[0,0,0,0],
[0,0,0,0],
[0,0,0,0]]

result = np.dot(A,B)

for r in result:
print(r)
Output:

[114, 160, 60, 27]
[74, 97, 73, 14]
[119, 157, 112, 23]
