    "quizzes": [0.0, 75.0, 78.0],
    "tests": [100.0, 100.0]
}

# Add your function below!
students = [lloyd,alice,tyler]
def average(numbers):
    total = sum(numbers)
    total = float(total)
    total = total / len(numbers)
    return total
def get_average(student):
        homework = average(student["homework"])
        quizzes = average(student["quizzes"])
        tests = average(student["tests"])
        return (homework *.1) + (quizzes *.3) + (tests *.6)
print get_average(alice)
def get_letter_grade(score):
    if score >= 90:
        return "A"
    elif score >= 80:
        return "B"
    elif score >= 70:
        return "C"
    elif score >= 60:
        return "D"
    else:
        return "F"
def get_class_average(students):
    results = []
    for student in students:
        result = get_average(student)
        results.append(result)
    return average(results)
print "The class average is %s" % get_class_average(students)
print get_letter_grade(students)
    
this is what it prints : 
91.15
The class average is 83.8666666667
A
None

You need to just write this line like this,

print get_class_average(students)

No string formatting is required, because to pass the SCT only an integer should be logged to the console. :slight_smile:


#3

at start i did do that, said same thing


#4

now it says did u remember to print the letter grade, but it did print it..


#5

You did not print get_letter_grade correctly because you did not include the get_class_average function as required,

should be,

print get_letter_grade(get_class_average(students))
