Test Average and Grade – Python

Test Average and Grade – Python

To have it print the letter grade as a user enters a score you can do something like:

#Calculate average
def calc_average(total):
    return total / 5

#Grading scale
def determine_score(grade):
    if 90 <= grade <= 100:
        return A
    elif 80 <= grade <= 89:
        return B
    elif 70 <= grade <= 79:
        return C
    elif 60 <= grade <= 69:
        return D
    else:
        return F

#Enter 5 test scores
scores = []
for i in range(1, 6):
    score = int(input(Enter score {0}: .format(i)))
    print Thats a(n):  + determine_score(score)
    scores.append(score)

total = sum(scores)
avg = calc_average(total)
abc_grade = determine_score(avg)


print(Average grade is:  + str(avg))
print(Thats a(n):  + str(abc_grade))

The letter grade problem was that you were using total which was all the grades added up (hopefully more than 100 if you got at least a 20 on all 5 assignments), so it would always default to the else. You want to use the avg so that it would give you the letter grade corresponding to the average:

abc_grade = determine_score(avg)

You can also omit the grade = total line because you will never use grade after making this change.

As said previously, if you want to get the correct grade letter you need to change your code from:

abc_grade = determine_score(grade)

to:

abc_grade = determine_score(avg)

Im not 100% sure what you meant in your last question where you asked how to display the grade letter after the average grade but if i understood you correctly you can just do this:

print The average grade is: %s and the grade letter of the average is: %s  % (str(avg), abc_grade)
