Help! when i try to run my code this error comes up: get_class_average([alice]) resulted in an error: 'float' object has no attribute 'append'

this is what i wrote:

  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):# Add your function below!
    total = sum(numbers)
    total = float(total)
    total = total / len(numbers)
    return total

def get_average(student):
    homework = average(student['homework'])
    quizzes = average(student['quizzes'])
    tests = average(student['tests'])
    return homework * 0.10 + quizzes * 0.30 + tests * 0.60
    
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))

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

Please be kind I'm a newbie :3

This list needs to be in global scope. Move it outside of the function, then pass it in.
