<In what way does your code behave incorrectly? Include ALL error messages.>

I get the error:

get_class_average([alice]) returned 83.8666666667 instead of 91.15 as expected

<What do you expect to happen instead?>

Not quite sure what’s causing the bug. Please help. Here’s 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]

}

# Add your function below!

def average(numbers):

total = sum(numbers)

total = float(total)

return total / len(numbers)

def get_average(student):

homework = average(student[“homework”]) * 0.1

quizzes = average(student[“quizzes”]) * 0.3

tests = average(student[“tests”]) * 0.6

return homework + quizzes + 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”

def get_class_average(students):

results =

school_class = [lloyd, alice, tyler]

for student in school_class:

results.append(get_average(student))

return average(results)
