# Multiplication of two matrix in python

Python program for Multiplication of two matrix. Here mentioned other language solution.

``````#  Python 3 program for
#  Two matrix multiplication

#  Display the element of given 2d matrix
def printRecord(matrix) :
print(" ",matrix)

def multiplication( a,  b) :
#  Get the size
row = len(a)
col = len(a[0])
#  This matrix are store the result of multiplication
result = [[0] * (col) for _ in range(row)]
i = 0
while (i < row) :
j = 0
while (j < col) :
#  Set the initial value of new matrix element
result[i][j] = 0
k = 0
while (k < row) :
#  Multiply matrix A [i] row and [k] columns to
#  the Matrix B [k] columns and [j] rows.
result[i][j] += a[i][k] * b[k][j]
k += 1
j += 1
i += 1
print("  Matrix A")
#  Print element of matrix x
printRecord(a)
print("  Matrix B")
#  Print element of matrix y
printRecord(b)
print("  Matrix [(A) x (B)]")
#  Display resultant matrix
printRecord(result)

if __name__=="__main__":
#  Define matrix A
a = [[1, 2, 3], [6, 1, 2], [5, 4, 3]]
#  Define matrix B
b = [[3, 1, 3], [1, 1, 2], [2, 2, 3]]
multiplication(a, b)``````

Output

``````  Matrix A
[[1, 2, 3], [6, 1, 2], [5, 4, 3]]
Matrix B
[[3, 1, 3], [1, 1, 2], [2, 2, 3]]
Matrix [(A) x (B)]
[[11, 9, 16], [23, 11, 26], [25, 15, 32]]``````
