Please create a python module named homework.py and implement the classes and methods outlined below. Below you will find an explanation for each class and method you need to implement. When you are done please upload the file homework.py to Grader Than. Please get started as soon as possible on this assignment. This assignment has many problems, it may take you longer than normal to complete this assignment. 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. Class Assignment This object represents a school assignment that a student will work on.
__init__(self, name: str, difficulty: float):
""" Constructs an assignment with the given assignment name and a float that indicates the level of difficulty of the assignment. :param name: The name of the assignment :param difficulty: The level of difficulty of the assignment
"""
name(self) -> str:
"""
Returns the name of the assignment as specified in the constructor. :return: The assignment name

"""
__str__(self) -> str:
"""

"""
Class AssignmentResult An object that represents the result of an assignment.
__init__(self, id:int, assignment: Assignment, grade: float):
"""
This will contain the ID of the student, the assignment that the student worked on and the grade the student received on the assignment. :param id: The ID of the student that created this Assignment result :param assignment: The Assignment that the student worked on. :param grade: A number between 0-1 representing the numerical grade the student received

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. :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

"""
grade(self)->float:
"""
Calculates a an average grade based off of the student's past assignment's grades. 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.

"""
assign(self, assignment:Assignment) -> AssignmentResult:
"""
This function is to simulate the process of the student receiving an assignment, then working on the assignment, then submitting the assignment and finally receiving grade for the assignment. 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. So if they sleep for 8 hours there energy will be restored by 80%. If they have 50% (.5) energy and sleep for 8 hours the will wake up with 90% energy = (.5 * (1+.8)). The max energy a s student may have is 100% (1) :param hours: The number of hours a student will sleep for. Example: .2 is equal to 12 minutes or 20% of an hour. :return: None

can someone help me on this Q with some explanation ? thank you in advance!

As you know this assignment is large, I cant answer this completely in one question,
The parital answer was here.
I had completely implemented the first two calss and the part of the Student class.
class Assignment:
def __init__(self, name: str, difficulty: float):
self.name = name
self.difficulty = difficulty
def name(self) -> str:
return(self.name)
def difficulty(self) -> str:
return(self.difficulty)
def __str__(self) -> str:
return(self.name)
class AssignmentResult:
def __init__(self, id:int, assignment: Assignment, grade: float):
self.id = id
self.assignment = assignment
self.grade = grade
def id(self) -> int:
return(self.id)
def grade(self) -> float:
return(self.grade)
def assignment(self) -> Assignment:
return(self.assignment)
class Student:
def __init__(self, id: int, fist_name: str, last_name: str, town:str):
self.id = id
self.fist_name = fist_name
self.last_name = last_name
self.town = town
def id(self) -> int:
return(self.id)
def first_name(self) -> str:
return(self.fist_name)
def last_name(self) -> str:
return(self.last_name)
def town(self) -> str:
return(self.town))
def set_last_name(self, name: str):
self.last_name = name
def set_town(self, town: str):
self.town = town
def assignment(self) -> Assignment:
return(self.assignment)
def __str__(self) -> str:
return(self.first_name+" " + self.last_name)
Please post one more question .Dont copy paste the code, But ask for the remaining part of the answer in the question.
