HI...here is my code.. and i dont know whyyyy this Error comes out "Oops, try again. get_class_average([alice]) returned 83.8666666667 instead of 91.15 as expected"

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)
result = total / len(numbers)
return result

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

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"

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

Hi @ihayko,

This should be moved to outside the get_class_average function ...

students = [lloyd, alice, tyler]
`
