Using Python I need to Prompt the user to enter in a numerical score for a Math Class. The numerical score should be between 0 and 100. Prompt the user to enter in a numerical score for a English Class. The numerical score should be between 0 and 100. Prompt the user to enter in a numerical score for a PE Class. The numerical score should be between 0 and 100. Prompt the user to enter in a numerical score for a Science Class. The numerical score should be between 0 and 100. Prompt the user to enter in a numerical score for an Art Class. The numerical score should be between 0 and 100. Call the letter grade function 5 times (once for each class). Output the numerical score and the letter grade for each class.

The program doesn't use comments; See explanation section for detailed line by line explanation

Program starts here

def lettergrade (subject, score):

print (subject+": "+str (score))

if score > = 90 and score < = 100:

print ("Letter Grade: A")

elif score > = 80 and score < = 89:

print ("Letter Grade: B")

elif score > = 70 and score < = 79:

print ("Letter Grade: C")

elif score > = 60 and score < = 69:

print ("Letter Grade: D")

elif score > = 0 and score < = 59:

print ("Letter Grade: F")

else:

print ("Invalid Score")

maths = int (input ("Maths Score: "))

english = int (input ("English Score: "))

pe = int (input ("PE Score: "))

science = int (input ("Science Score: "))

arts = int (input ("Arts Score: "))

lettergrade ("Maths Class: ", maths)

lettergrade ("English Class: ", english)

lettergrade ("PE Class: ", pe)

lettergrade ("Science Class: ", science)

lettergrade ("Arts Class: ", arts)

Explanation:

The program makes the following assumptions:

Scores between 90-100 has letter grade A

Scores between 80-89 has letter grade B

Scores between 70-79 has letter grade C

Scores between 60-69 has letter grade D

Scores between 0-69 has letter grade E

Line by Line explanation

This line defines the lettergrade functions; with two parameters (One for subject or class and the other for the score)

def lettergrade (subject, score):

This line prints the the score obtained by the student in a class (e. g. Maths Class)

print (subject+": "+str (score))

The italicized determines the letter grade using if conditional statement

This checks if score is between 90 and 100 (inclusive); if yes, letter grade A is printed

if score > = 90 and score < = 100:

print ("Letter Grade: A")

This checks if score is between 80 and 89 (inclusive); if yes, letter grade B is printed

elif score > = 80 and score < = 89:

print ("Letter Grade: B")

This checks if score is between 70 and 79 (inclusive); if yes, letter grade C is printed

elif score > = 70 and score < = 79:

print ("Letter Grade: C")

This checks if score is between 60 and 69 (inclusive); if yes, letter grade D is printed

elif score > = 60 and score < = 69:

print ("Letter Grade: D")

This checks if score is between 0 and 59 (inclusive); if yes, letter grade F is printed

elif score > = 0 and score < = 59:

print ("Letter Grade: F")

If input score is less than 0 or greater than 100, "Invalid Score" is printed

else:

print ("Invalid Score")

This line prompts the user for score in Maths class

maths = int (input ("Maths Score: "))

This line prompts the user for score in English class

english = int (input ("English Score: "))

This line prompts the user for score in PE class

pe = int (input ("PE Score: "))

This line prompts the user for score in Science class

science = int (input ("Science Score: "))

This line prompts the user for score in Arts class

arts = int (input ("Arts Score: "))

The next five statements is used to call the letter grade function for each class

lettergrade ("Maths Class: ", maths)

lettergrade ("English Class: ", english)

lettergrade ("PE Class: ", pe)

lettergrade ("Science Class: ", science)

lettergrade ("Arts Class: ", arts)
