YOU MUST USE PYTHON WITH NUMPY

I3=100010001 We always denote the identity matrix with a capital I. Often a subscript is used to denote the value of n. The notations Inxn and In are both acceptable. An identity matrix is similar to the number 1 for scalar values. I.e. multiplying a square matrix Anxn by its corresponding identity matrix Inxn (either on the left or on the right) results in itself Anxn. Pick a random 33 matrix (you can define it using np.matrix (np. random. random ([3,3]) )), A, and multiply it by the 33 Identity matrix (once on the left and once on the right) and show you get A in either case, i.e. demonstrate that AI3=A and I3A=A. Consider two square matrices A and B of size nn.AB=BA is NOT true for many A and B. Describe an example (different from the one above) where AB=BA is true. Explain why the equality works for your example
