Write a Python class Matrix which defines a two-by-two matrix with float entries as a Python object. The class Matrix has to be able to display the object on the screen when the print function is called, and it should include methods determinant(), trace(), inverse(), characteristic_polynomial(), and matrix_product(). Furthermore, a user should be able to multiply the matrix by a constant and be able to add and subtract two matrices using the usual symbols + and -. Use the following...
