# 6/9 Can't get the weighted average to come out right

#1

So I've looked at other topics to help, and I've even copied and pasted code to see if I'm just messing up syntax or something. But when I click 'save and submit code' an error pops up and I don't understand it at all. Help would be much appreciated!!!

Here is my codebit for you to study. From what I can see you are doing the math correctly but who knows with the judge on here.

MY CODE:

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

I tried it and it still came up with that error, I sort of think it has to do with the first average part or the original numbers even though they were given to us... I don't know, this is weird. But thank you for your help

Below is the whole code I have that passes, compare it to yours.

It's for 9/9 btw.

``````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):
return sum(numbers) // len(numbers)

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

if score >= 90:
return "A"
elif score >= 80:
return "B"
elif score >= 70:
return "C"
elif score >= 60:
return "D"
else:
return "F"

students = [lloyd, tyler, alice]

def get_class_average(students):
return average([get_average(student) for student in students])

print get_class_average(students)

It's cheating, I know... I copied your code just to see if it would work for me since it worked for you. And it returned 91 instead of 91.5. I just switched out your def average(numbers) bit of code for mine and it worked wonderfully!! Thank you so much for your help!!

This is how wrote the code. Just in case anyone wants to look it over.
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

#7

I've shortened the code.

def get_average(student):
return .1 * average(student["homework"]) + .3 * average(student["quizzes"]) + .6 * average(student["tests"])

#9
