Python Program to multiply two matrices using nested loops

# Program to multiply two matrices using nested loops

# 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 = [[0, 0, 0, 0],
[0, 0, 0, 0],
[0, 0, 0, 0]]

# iterating by row of A
for i in range(len(A)):

# iterating by column by B
for j in range(len(B[0])):

# iterating by rows of B
for k in range(len(B)):
result[i][j] += A[i][k] * B[k][j]

for r in result:
print(r)
Output:

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