# 8/9 idk what is wrong

lloyd = {
"name": "Lloyd",

"quizzes": [88.0, 40.0, 94.0],

alice = {

def average(numbers):
total = sum(numbers)
total = float(total)
if score >= 90:
return "A"
elif score >= 80:
return "B"
elif score >= 70:
return "C"
elif score >= 60:
return "D"
else:
return "F"

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

def get_class_average(student):
results = []
for student in student:
results.append(average(student))
return average(results)

I have no idea what is wrong im getting
"Oops, try again. get_class_average([alice]) resulted in an error: unsupported operand type(s) for +: 'int' and 'str'"
Thanks for any help

It's never a good idea to use the same name for a iterator variable and parameter:

``for student in student:``

I would change the name of the parameter to `students` or `class` as it should represent list of students.

Read again this part of instruction and check if you did it correctly:

For each `student` item in the `class` list, calculate `get_average(student)` and then call `results.append()` with that result.

Make sure you have all your indentation correct. I've been stuck on this for the better part of 2 days only to sit down and finally notice my return was in the wrong spot.
