You could use numpy library by using matmul(MatrixA,MatrixB) method.

In this method matmul you can pass two arguments "MatrixA" & "MatrixB" and it will multiply both matrixes together

Usage

import numpy as np

# Matrix A
A = [[2, 4],
      [6, 8]]

# Matrix B      
B = [[1, 3],
      [5, 7]]
 
"""
It will do the following:
A = [[2,4],[6,8]]
B = [[1,3],[5,7]]

After running the method
C = [[2*1, 4*3],[6*5, 8*7]] = [[2, 12],[30, 56]]
"""
print(np.matmul(A,B))
