Chapter 7 Exercise Set 1: Doctest Exercises

In each of the following exercises, write Python code to make the doctests pass.

1. class Student:
       """
         >>> student = Student('Gizelle', 'Day', 11)
         >>> student.fname
         'Gizelle'
         >>> student.lname
         'Day'
         >>> student.grade
         11
       """
   

2. class Polynomial:
       """
         >>> p1 = Polynomial()
         >>> print(p1)
         '0'
         >>> p2 = Polynomial([3, 1, 5])
         >>> print(p2)
         '3x^2 + x + 5'
         >>> p3 = Polynomial([2, 3, 1, 5])
         >>> print(p3)
         '2x^3 + 3x^2 + x + 5'
         >>> p4 = Polynomial([2, 0, 3, 7, 2])
         >>> print(p4)
         '2x^4 + 3x^2 + 7x + 2'
