I keep getting the error message:
get_average(alice) raised the following error: unsupported operand type(s) for /: 'float' and 'list'

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]

# Add your function below!
def average(numbers):
    total = sum(numbers)
    total = float(total)
    len(total / numbers)
    return total
    
def get_average(student):
    homework = (average(student["homework"]) * 0.10)
    quizzes = (average(student["quizzes"]) * 0.30)
    tests = (average(student["tests"]) * 0.60)
    return homework + quizzes + tests

even i'm getting a similar error

Oops, try again.
get_average(alice) raised the following error: list indices must be integers, not str
my code is as follows

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