Hi there!

Soooo my question is:

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]

}def average(numbers):

total = sum(numbers)

total = float(total)

return total / len(numbers)def get_average(student):

homework = average(student["homework"])

quizzes = average(student["quizzes"])

tests = average(student["tests"])

return sum(homework*0.1, quizzes*0.3, tests*0.6)

why doesn't this work?

I got the error: "Oops, try again. get_average(alice) raised the following error: sum expected at most 2 arguments, got 3 "

Therefore it has to to with the sum() function.

Because it works when removing the sum() function and just adding everything up.

Thanks for letting me understand this.
