How to Multiply Two Matrices in Terminal using Python

Submitted by razormist on Friday, March 7, 2025 - 22:49.

In this tutorial, we’ll learn how to program “How to Multiply Two Matrices in the Terminal Using Python.” The objective is to safely multiply two matrices in a list. This tutorial will guide you through the process step by step to identify matrices that can be multiplied together. So, let’s get started!

This topic is straightforward to understand. Just follow the instructions I provide, and you’ll complete it with ease. The program I’ll demonstrate will illustrate the correct way to multiply two matrices. So, let’s dive into the coding process!

Getting Started:

First you will have to download & install the Python IDLE's, here's the link for the Integrated Development And Learning Environment for Python https://www.python.org/downloads/.

Creating Main Function

This is the main function of the application. The following code will display a simple GUI in terminal console that will display program. To do this, simply copy and paste these blocks of code into the IDLE text editor.

matrix_a = [[5, 4], [1, 6]]
matrix_b = [[2, 3], [9, 7]]
 
result = [[0, 0], [0, 0]]
 
while True:
    print("\n================= Multiply Two Matrices =================\n\n")
 
    print("Matix A: ", matrix_a)
    print("\nMatix B: ", matrix_b)
    print("\n")
 
    print("Multiplied Matrices: ")
    for i in range(2):
        for j in range(2):
            result[i][j] = (matrix_a[i][0] * matrix_b[0][j] +
                            matrix_a[i][1] * matrix_b[1][j])
 
    for row in result:
        print(row)
 
    opt = input("\nDo you want to try again?(yes/no): ")
 
    if opt.lower() == 'yes':
            ret=False
    elif opt.lower() == 'no':
            ret=True
            print("Exiting program....")
    else:
            print("Please enter yes/no:")
            break
 
    if ret == False:
            continue

This program multiplies two 2×2 matrices (Matrix A and Matrix B) using the standard matrix multiplication formula. It calculates the dot product of rows from Matrix A with columns from Matrix B and stores the result in a new matrix. The program then prints the multiplied matrix and asks the user if they want to repeat the process or exit.

Output:
