# 8. Part of Whole, blunder

<Below this line, add a link to the EXACT exercise that you are stuck at.>
<In what way does your code behave incorrectly? Include ALL error messages.>
Oops, try again. get_class_average([alice, lloyd]) returned 91.15 instead of 85.85 as expected
<What do you expect to happen instead?>

```python

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):
numbers = list(numbers)
return float(sum(numbers)) / float(len(numbers))

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”

def get_class_average(students):
students = list(students)
results =
for x in students:
results.append(get_average(x))
return average(results)

``<do not remove the three backticks above>``

Hi your return average(results) should be inside the function get_class_average() and not inside the for loop

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

oh, Alright. Thanks a ton.
