I don't really know what's wrong with 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(len(numbers))

total=len(total/numbers)

return total

def get_average(student):

homework=average(["homework"])

quizzes=average(["quizzes"])

tests=average(["tests"])

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

Then it shows

**

## Oops, try again. get_average(alice) raised the following error: unsupported operand type(s) for /: 'float' and 'list'

**

Please help!

Thank you
