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]
}

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

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

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):
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.
