In this tutorial, you will learn to multiply two matrices in Python. A matrix is a two-dimensional data structure where numbers are arranged into rows and columns. Python does not have a built-in type for matrices but we can treat a nested list or list of a list as a matrix. TheList...

In themain()function, we created three 2X2 matrices using a two-dimensional array, and then we read the elements forMatrix1andMatrix2from the user. Then we multiplyMatrix1andMatrix2and assign the result intoMatrix3. After that, we printed the multiplication of matrices on the console screen...
matrix_2d_random = np.random.choice(size = (3,3), a = numbers_1_to_9, replace = False) Once you have Numpy imported and once you’ve created the arrays, you’ll be ready to run the examples. EXAMPLE 1: Use the Numpy multiply on two scalars ...
