Write a python program that asks the user to enter a student's name and 8 numeric tests scores (out of 100 for each test). The name will be a local variable. The program should display a letter grade for each score, and the average test score, along with the student's name. There are 12 students in the class.

Write the following functions in the program:

calc_average - this function should accept 8 test scores as arguments and return the average of the scores per student

determine_grade - this function should accept a test score average as an argument and return a letter grade for the score based on the following grading scale:

90-100        A

80-89          B

70-79          C

60-69          D

Below 60     F

Answer:

def determine_grade(score):
    if score >=90:
        return 'A'
    elif score >=80 and score <90:
        return 'B'
    elif score >=70 and score <80:
        return 'C'
    elif score >=60 and score <70:
        return 'D'
    else:
        return 'F'
def calc_average(scores):
    total = 0
    for i in range(len(scores)):
        total = total + scores[i]
    return total/float(len(scores))

scores = []
name = input("Enter the student name: ")
for i in range(8):
    score = int(input("Enter the score: "))
    scores.append(score)
averageScore = calc_average(scores)
print("Student Name: ", name)
for i in range(len(scores)):
    print("Score: ",scores[i], "Letter Grade: ",determine_grade(scores[i]))
print("Average Score: ", averageScore)

Output:

$python3 main.py
Enter the student name: 55
Enter the score: 66
Enter the score: 77
Enter the score: 88
Enter the score: 99
Enter the score: 22
Enter the score: 33
Enter the score: 44
