Write a function class-average that takes a list of student objects as its argument and returns the aver age grade earned by students in the list. Note that your class-average function should call the grade method (which you wrote in Part I) on each Student object to get that student's grade in the course. Take the simple, unweighted average of all students' grades to compute the class average
