# Add your function below!

def average(numbers):
    total = sum(numbers)
    total = float(total)
    total = total / len(numbers)
    return total

students = [lloyd, alice, tyler]
    
def get_average(student):
    homework = average(student["homework"])
    quizzes = average(student["quizzes"])
    tests = average(student["tests"])
    homework = .1 * homework
    quizzes = .3 * quizzes
    tests = .6 * tests
    return (homework + quizzes + tests)
    
def get_letter_grade(score):
        score = float(score)
        if score >= 90:
            return 'A'
        elif score >= 80: 
            return 'B'
        elif score >= 70: 
            return 'C'
        elif score >= 60: 
            return 'D'
        else:
            return 'F'
print get_letter_grade(get_average(lloyd))

def get_class_average(students):
    
    results = []
    for student in students:
        get_average(student)
        results.append(get_average(student))
        
        return average(results)

When I submit the above code, I am told: Oops, try again.
get_class_average([alice, lloyd]) returned 91.15 instead of 85.85 as expected

I am a novice. Therefore, this confuses me.
Thank you for your help

"""try to see if adding""" for number in numbers:
"""under def average and change all the (numbers) after that to (number)"""


#3
def average(numbers):
   for number in numbers:
       total = sum(number)
       total = float(total)
       total = total / len(number)
       return total

Is this what you mean? If it is, it did not work. Thanks for the help though.

try moving this back one indent (4 spaces backward)
return must always be on the same indent as a "for" statement
