Question

This assignment is supposed to represent a group of students in a course. A group of students in a course will be assigned an assignment and produce a collection of assignment results. The results will be used to figure out grade statistics. The grade they receive for their work on the assignment is entirely dependant on the student's energy level. If the student works on many assignments without sleeping their grade will suffer. You will implement four classes (Assignment, AssignmentResult, Student, and Course), they will depend on each other in the order they are listed. Hint:  Work on the methods in the order they are found in the documentation below, implement the getter and setter methods before the more complicated methods. Work on the Assignment class, AssignmentResult class, Student class and Course class in that order. Make sure you don't name your class variables the same name as you class's methods. In other words if you have method named id you cannot have a class variable named self.id. To avoid name conflicts often developers will start the name of their class variables with 2 underscores &#34;_&#34;. For example self.__id = 123 Class CourseThis class represents a course that a group of students is enrolled in. They will be assigned assignments when enrolled in this course.
