I'm really confused about what I've done wrong, it says I'm trying to times an integer by a float, but I don't really understand why...

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)

average = total / len(numbers)

return average

def get_average(student):

homework = [average(student["homework"])]

quizzes = [average(student["quizzes"])]

tests = [average(student["tests"])]

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

```
