Muliply two matrices

Two matrices $A$ and $B$ are given as follows:

A = [0.5 -1.0 -0.9];
B = [0.1; -0.6; -0.6];

import numpy as np

A = np.array([[0.5, -1.0, -0.9]])
B = np.array([[0.1], [-0.6], [-0.6]])

from sympy import *

A = Matrix([[0.5, -1.0, -0.9]])
B = Matrix([[0.1], [-0.6], [-0.6]])

Find the product of these two matrices:

$AB=$
