What am i doing wrong i am getting this error message: Oops, try again. get_average(alice) raised the following error: 'float' object is not iterable


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 = float(sum(numbers))
    result = total / len(numbers)
    return result
    
def get_average(student):
    homework = average(student["homework"])
    quizzes = average(student["quizzes"])
    tests = average(student["tests"])
    return sum(homework * .1) + (quizzes * .3) + (tests * .6)

I can't help with the explanation, but this is what I did to make it work.

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


#3

maybe having the sum() in the last line? try and remove it, or to have a parenthesis for it around the entire line, not just the homework function. youroperatorhere looks cleaner/wiser than what i came up with, but heres what i got:

def get_average(student):
homework = average(student["homework"])
quizzes = average(student["quizzes"])
tests = average(student["tests"])
return (.10 * average(student["homework"])) + (.3 * average(student["quizzes"])) + (.6 * average(student["tests"]))


#4

the sum function only takes integers, math.fsum() takes floats. you could simply return (homework*.1 + quizzes*.3 + test*.6)
