``````Can someone help me? I dont understand whats wrong.
Getting this all the time
**"get_class_average([alice, lloyd]) returned 91.15 instead of 85.85 as expected"**

my code 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)

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

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

Thank you<3``````

Here:

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

Are you sure that this `return` statement should be inside the `for` loop?

#3

I am getting the same problem? and I can't seem to see differences in the replies people are giving?

#4

Can you explain why the return statement should not be indented?

#5

Sure.

`return` statement terminates execution of the function.

So let's say that we have the list `[alice, lloyd]`. We enter the `for` loop and now `student = alice`. We append `get_average(alice)` to `results` and we return `average(results)`. This is the end of the function.

What about `lloyd`? His average is not included in the `results`. That is why `return` must be placed after `for` loop.
