# Help on 'Part of the whole'

I had a hard time understanding this exersises instructions and whenever I run my code I get this error message: get_class_average([alice]) resulted in an error: unsupported operand type(s) for +: 'int' and 'dict'

``````Replace this line with your code.

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)
total /= len(numbers)

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

return homework + quizzes + tests

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

print (get_average(lloyd))

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

This line has too much indentation, for one; and, it is passing the wrong object to `average`. It should be `result` that is passed in.

okay, thank you! this definitely helped
