    Python Code: This is my solution:

    class Person:
	def __init__(self, firstName, lastName, idNumber):
		self.firstName = firstName
		self.lastName = lastName
		self.idNumber = idNumber
	def printPerson(self):
		print("Name:", self.lastName + ",", self.firstName)
		print("ID:", self.idNumber)
		
class Student(Person):
    #   Class Constructor
    #   
    #   Parameters:
    #   firstName - A string denoting the Person's first name.
    #   lastName - A string denoting the Person's last name.
    #   id - An integer denoting the Person's ID number.
    #   scores - An array of integers denoting the Person's test scores.
    #
    # Write your constructor here
    def __init__(self, firstName, lastName, idNumber, scores):
        Person.__init__(self, firstName, lastName, idNumber)
        self.scores = scores
        

    #   Function Name: calculate
    #   Return: A character denoting the grade.
    #
    # Write your function here
    def calculate(self):
        average = sum(self.scores)/ len(self.scores)
        letter = '' "
        
        if average < 40:
            letter = 'T'
        elif 40 <= average < 55:
            letter = 'D'
        elif 55 <= average < 70:
            letter = 'P'
        elif 70 <= average < 80:
            letter = 'A'
        elif 80 <= average < 90:
            letter = 'E'
        elif 90 <= average <= 100:
            letter = 'O'
        return(letter)
        

line = input().split()
firstName = line[0]
lastName = line[1]
idNum = line[2]
numScores = int(input()) # not needed for Python
scores = list( map(int, input().split()) )
s = Student(firstName, lastName, idNum, scores)
s.printPerson()
print("Grade:", s.calculate())

    Java Solution

    class Student extends Person{
	private int[] testScores;
    
    Student(String firstName, String lastName, int id, int[] scores){
        super(firstName, lastName, id);
        this.testScores = scores;
    }

    char calculate() {
        int myScore = 0;
        for(int i : testScores) myScore += i;
        myScore /= testScores.length;

        char myResult = (
          (myScore>=90)?'O':
          (myScore>=80)?'E':
          (myScore>=70)?'A':
          (myScore>=55)?'P':
          (myScore>=40)?'D':
          'T'
        );
        
        return(myResult);
    }
    
}

    in c#

    class Student : Person{ private int[] testScores; 

    public Student(string firstName,string lastName,int id,int[] scores):
base(firstName,lastName,id)
{
            testScores=scores;
}

public char Calculate()
{
   int avg= testScores.Sum() /testScores.Count();

    switch(avg)
    {
        case int n when n>=90 &&  n<=100:
            return 'O';
            break;
        case int n when n>=80 && n<90:
            return 'E';
            break;
        case int n when n>=70 && n<80:

            break;
