get_class_average([alice, lloyd]) returned 80.55 instead of 85.85 as expected

always show the same problem. I've tried . i don't know what is the problem

``````Replace this line with your 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 = {

"homework": [100.0, 92.0, 98.0, 100.0],
"quizzes": [82.0, 83.0, 91.0],

tyler = {

"tests": [100.0, 100.0]
}

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

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

return homework + quizzes + tests

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

why define results inside the loop? This means, each iteration of your loop, results becomes empty again, things you append won't persist
