needed help keeps getting error

Oops, try again. get_class_average([alice, lloyd]) returned 91.15 instead of 85.85 as expected

``````lloyd = {
"name": "Lloyd",
"homework": [90.0, 97.0, 75.0, 92.0],
"quizzes": [88.0, 40.0, 94.0],
"tests": [75.0, 90.0]
}
alice = {
"name": "Alice",
"homework": [100.0, 92.0, 98.0, 100.0],
"quizzes": [82.0, 83.0, 91.0],
"tests": [89.0, 97.0]
}
tyler = {
"name": "Tyler",
"homework": [0.0, 87.0, 75.0, 22.0],
"quizzes": [0.0, 75.0, 78.0],
"tests": [100.0, 100.0]
}

def average(numbers):
sum(numbers)
total = sum(numbers)
total = float(total)
result = total / len(numbers)
return result
def get_average(student):
homework = average (student["homework"])
quizzes = average (student["quizzes"])
tests = average (student["tests"])
grade =( 0.1*homework) + (0.3*quizzes) + (0.6*tests)
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:
results.append(get_average(student))
return average(results)``````

The indentation of the return statement should line up with `for` so it is not inside the loop.
