Day_12_Inheritance.py

# Objective
# Today, we're delving into Inheritance. Check out the attached tutorial for learning materials and an instructional video.

# Task
# You are given two classes, Person and Student, where Person is the base class and Student is the derived class. Completed code for Person and a declaration for Student are provided for you in the editor. Observe that Student inherits all the properties of Person.

# Complete the Student class by writing the following:

# A Student class constructor, which has  parameters:
# A string, .
# A string, .
# An integer, .
# An integer array (or vector) of test scores, .
# A char calculate() method that calculates a Student object's average and returns the grade character representative of their calculated average:
# Grading.png

# Input Format

# The locked stub code in the editor reads the input and calls the Student class constructor with the necessary arguments. It also calls the calculate method which takes no arguments.

# The first line contains , , and , separated by a space. The second line contains the number of test scores. The third line of space-separated integers describes .

# Constraints

# Output Format

# Output is handled by the locked stub code. Your output will be correct if your Student class constructor and calculate() method are properly implemented.

# Sample Input

# Heraldo Memelli 8135627
# 2
# 100 80
# Sample Output

#  Name: Memelli, Heraldo
#  ID: 8135627
#  Grade: O
# Explanation

# This student had  scores to average:  and . The student's average grade is . An average grade of  corresponds to the letter grade , so the calculate() method should return the character'O'.
