Write a program that asks the user to enter five test scores. The program should display a letter grade for each score and the average test score. Write the following functions as part of the program:

calc_average: This function should accept five test scores as arguments and return the average of the scores.

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

Score Letter grade

90-100 A

80-89 B

70-79 C

60-69 D

Below 60 F

def calc_average (s1, s2, s3, s4, s5):

return (s1 + s2 + s3 + s4 + s5) / 5

def determine_grade (s):

if 90 < = s < = 100:

return "A"

elif 80 < = s < = 89:

return "B"

elif 70 < = s < = 79:

return "C"

elif 60 < = s < = 69:

return "D"

else:

return "F"

scores = []

for i in range (5):

scores. append (int (input ("Enter a test score: ")))

print (determine_grade (scores[i]))

print (str (calc_average (scores[0], scores[1], scores[2], scores[3], scores[4])))

Explanation:

Create a function called calc_average that takes 4 test scores, calculates their average, and returns the average

Create a function called determine_grade that takes a test score, returns the grade depending on the grading scale

Create an empty lists that will hold the test scores

Create a for loop to get test scores from the user. After getting a score, call the determine_grade function to determine the grade of the score

When the loop is done, call the calc_average function to calculate the average of the given test scores
