# Python program to multiply two matrices

In this article, we will learn about the solution to the problem statement given below.

**Problem statement **− We are given two matrices, we need to multiply them and print the result.

For two matrices to be multiplied columns of the first matrix must be identical to that of the rows of the second matrix

Each time this condition is evaluated to be true computation is performed

Now let’s observe the concept in the implementation below−

## Approach 1 − Brute-force method

### Example

A = [[1, 2, 3], [4, 5, 6], [7, 8, 9] ] B = [[5, 3, 3], [6, 5, 4], [0, 2, 0] ] result= [[0, 0, 0], [0, 0, 0], [0, 0, 0] ] # iterating by row for i in range(len(A)): # iterating by column for j in range(len(B[0])): # iterating by rows for k in range(len(B)): result[i][j] += A[i][k] * B[k][j] for ele in result: print(ele)

### Output

[17, 19, 11] [50, 49, 32] [83, 79, 53]

## Approach 2 − Using zip function

### Example

A = [[1, 2, 3], [4, 5, 6], [7, 8, 9] ] B = [[5, 3, 3], [6, 5, 4], [0, 2, 0] ] # using built-in zip function result = [[sum(a * b for a, b in zip(A_row, B_col)) for B_col in zip(*B)] for A_row in A] for ele in result: print(ele)

### Output

[17, 19, 11] [50, 49, 32] [83, 79, 53]
