Oops, try again. get_class_average([lloyd]) returned 85.85 instead of 80.55 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]
}
students = ["llyod", "alice", "tyler"]

Add your function below!

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

def get_average(student):
homework = average(student["homework"])
quizzes = average(student["quizzes"])
tests = average(student["tests"])
return (homework*0.1 + quizzes*0.3 + tests*0.6)

def get_letter_grade(score):
if score>=90:
return "A"
elif score>=80 and score<90:
return "B"
elif score>=70 and score<80:
return "C"
elif score>=60 and score<70:
return "D"
else:
return "F"

print get_letter_grade(get_average(lloyd))

results = []

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

Hi the instruction says...
02. First, make an empty list called results.
so you should put it inside the function get_class_average

Thank you!
It worked out!
