# 2) A program is required that accepts marks in three subjects and calculates the average mark. The program then
# assigns the student a grade based on the average mark using the grading system below.
# Average Mark Grade
# 80 – 100 A
# 70 – 80 B
# 60 – 70 C
# 50 – 60 D
# 0 – 50 E
# i) Write a program with a function called get_grade which accepts the
# average mark and returns the grade to the main function which then outputs it.                                  (8
# marks)

# ii) Write a program with a function called grade which accepts the average mark and prints the grade.
