In Python 3, write a function that takes two arguments, (1) an n x m matrix and (2) a 1 x n matrix, and that multiplies each row by the corresponding index of the scaling matrix. For example, f(A, [3, 10]), would operate on a 2 x m matrix A and multiply each element of the first row by 3 and the second row by 10. For clarity, please use Markdown formatting around your actual code sample. That is, three back ticks (`) to open the block of code and three more to close it. Note that you are more than welcome to use a library like NumPy.
