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 "_". For example self.__id = 123 Class Student This class represents a single student __init__(self, id: int, fist_name: str, last_name: str, town:str): """ This creates a student object with the specified ID first and last name and home town. This constructor should also create data structure for holding the students grades for all of there assignments. Additionally it should create a variable that holds the student's energy level which will be a number between 0 and 1. The student start out with 1 (100%) energy. :param id: The student's identifiaction number :param fist_name: The student's first name :param last_name: The student's last name :param town: The student's home town """ get_id(self)->int: """ Returns the ID of the student as specified in the constructor. :return: The student's ID """ get_first_name(self) -> str: """ Returns the first name of the student. :return: The student's first name """ set_first_name(self, name:str): """ Changes the student first name to the specified value of the name parameter. :param name: The value that the first name of the student will equal.

The lowest grade is not included in the grade calculation if the student has been assigned to two or more assignments in the past. See assign() for more detains.

This function will receive an assignment then a grade should be calculated using the following formula: grade = 1 - (Student's current energy X Assignment difficulty level). The min grade a student may receive is 0% (0) After the grade is calculated the student's energy should be decreased by percentage difficulty. Example if the student has 80% (.8) energy and the assignment is a difficultly level .2 there final energy should be 64% (.64) = .8 - (.8 * .2). The min energy a student may have is 0% (0) Finally the grade calculated should be stored internally with in this class so it can be retrieved later. Then an Assignment Result object should be created with the student's ID, the assignment received as a parameter, and the grade calculated. This newly created Assignment Result object should be returned. :return: The an AssignmentResult outlining this process """ sleep(self, hours:float): """ This function restore the student's energy as a rate of 10% per hour.
