5) Matrix Multiplication Write a Python function that takes two matrices A and B, checks if the inner dimensions are equal, and if so returns matrix C that is equal to the matrix product AB. Otherwise your code may print an error message (or raise an Exception) You should do this using a triply nested for loop : first create a matrix C of all zeros, then loop over all of the element of C, and then for each element of C compute the appropriate value using Validate your code by your own choosing matrices A and B and computing the matrix product using both your cod and the built-in matrix multiplication operator
