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


I am not sure why the error message is showing me get_class_average([alice, lloyd]). Why are alice and lloyd appearing together, and what happened to Tyler? Is Tyler missing from my average? Where did I go wrong that it is calculating alice and lloyd together? Code below. Thanks.


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]
}
#class_list = [lloyd, alice, tyler]

# Add your function below!
def average(numbers):
   total = sum(numbers)
   total = float(total)
   grade = total / len(numbers)
   return grade
   
def get_average(student):
    homework = average(student["homework"])
    quizzes = average(student["quizzes"])
    tests = average(student["tests"])
    weighted = homework * .1 + quizzes * .3 + tests * .6
    return weighted

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"

#print get_letter_grade(get_average(lloyd))

students = [lloyd, alice, tyler]

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

This error indicates an improperly indented return statement.

Thank you! That's all it needed--I forgot to un-indent the return.
