Hello, can you please help me too! i think i wrote correct code but it's still getting me the error:
Oops, try again. get_class_average([alice]) resulted in an error: 'list' object has no attribute 'appened'

Here is my code:

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

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

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"

get_letter_grade(get_average(lloyd))

students = [lloyd, alice, tyler]

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