This assignment creates a GradeBook class that manages a list of quiz grades, computes the average and maintains acount of GradeBook objects, one per student. Your program needs to support just two students. Here's how yourprogram should start:$ python3 hwk7.pyPlease enter the name for Student 1: MaryThere are 1 students in the GradeBook.Please enter the name for Student 2: HadalamThere are 2 students in the GradeBook.• countGrade Book0: Exit1: Enter quiz grade for Student 12: Enter quiz grade for Student 23: Display current grades for all students.Please enter a choice:When the program first starts up, the user is queried to enter the names for two students. A count of how manyGradeBook objects have been created is maintained in a class variable within GradeBook. This variable is to be updatedin the constructor and used for the display of the count. See class vs instance variables for reference.Your class should include the following methods:• a constructor - __init__(self, name). The construct should two instance variables, self.name and self.grades. The name parameter is stored inself.name and self.grades should be created as an empty list.quizScore(self, score). This method is called to add the score to self.grades• currentAverage(self)• This method computes the average of the scores in self.grades and returns the resultClass variables:this variable is used to count how many GradeBook objects have been createdGradeBook.count should be initialized to O outside of any of the methods.o GradeBook.count should be incremented by one inside of the constructorInstance variablesself.name the name of the student• self.grades the list of quiz scores for the studentEach GradeBook object (one per student) needs to be created before the while loop. Be sure to include the student'sname when creating the object.In order to test your GradeBook class, you'll implement a menu driven interface, providing the choices as shown in theimage above. When the user chooses to enter a quiz grade for Student 1, Student 1's quiz list should be updated. Whenthe user chooses to enter a quiz grade for Student 2, Student 2's quiz list should be updated. When the user chooses todisplay the current grades for all students, the averages for Student 1 is computed via currentAverage method andreturned to be printed in the main program (not in currentAverage), and then the same is done with Student 2. Thename of each student is available as instance variable in each object, e.g. student1.name, and should be included in thedisplay. That is, the names should not come from variables outside of the objects. For the purposes of this assignment,the number of students is fixed at two. You do not need to maintain a list of objects. Just use a separate variable foreach objecte.g. student1 and student2.If you have implemented the instance and class variables correctly, entering a score for one student should not changethe other student's average. If that happens, you are probably using a class variable instead of an instance variable forthe list of quiz scores.

GradeBook.count should be initialized to 0 outside of any of the methods. GradeBook.count should be incremented by one inside of the constructor Instance variables • self.name the name of the student • self.grades - the list of quiz scores for the student Each GradeBook object (one per student) needs to be created before the while loop. Be sure to include the student's name when creating the object. In order to test your GradeBook class, you'll implement a menu driven interface, providing the choices as shown in the image above. When the user chooses to enter a quiz grade for Student 1, Student 1's quiz list should be updated. When the user chooses to enter a quiz grade for Student 2, Student 2's quiz list should be updated. When the user chooses to display the current grades for all students, the averages for Student 1 is computed via currentAverage method and returned to be printed in the main program (not in currentAverage), and then the same is done with Student 2.
