Hi, im having trouble with this exercise. Please help me, I'm ready to pull out my hair.. Here is 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]

}

i keep getting the following error: get_average(alice) raised the following error: object of type 'float' has no len()

# Add your function below!

def average(numbers):

total = sum(numbers)

total = float(total)

total = float(total) / len(total)

return total

def get_average(student):

homework = average(student["homework"])

quizzes = average(student["quizzes"])

tests = average(student["tests"])

return homework * 0.1 + quizzes * 0.3 + tests * 0.6
