Question

Check our syllabus for the grading policy: A+: [97,infinity) A: [93,97) A-: [90,93) B+: [87,90) B: [83,87) B-: [80,83) C+: [77,80) C: [73,77) C-: [70,73) D+: [67,70) D: [63,67) D-: [60,63) F: [0,60) Write a function letterGrade(points) where the input points is a non-negative number. Use the python language to solve the problem. The function should return the letter grade.

Answer 1

def letterGrade(points):
    if(points>=97):
        return "A+"
    elif(points>=93):
        return "A"
    elif (points >= 90):
        return "A-"
    elif (points >= 87):
        return "B+"
    elif (points >= 83):
        return "B"
    elif (points >= 80):
        return "B-"
    elif (points >= 77):
        return "C+"
    elif (points >= 73):
        return "C"
    elif (points >= 70):
        return "C-"
    elif (points >= 67):
        return "D+"
    elif (points >= 63):
        return "D"
    elif (points >= 60):
        return "D-"
    else:
        return 'F'

# Testing
print(letterGrade(78))

Output:

C+
