# 8. Part of the Whole

#1

The final part of the code looks like the answer I see in other answer threads here, but i get the following error:
Oops, try again. get_class_average([alice]) resulted in an error: maximum recursion depth exceeded

Does anybody know how to fix this?

``````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)
return float(total) / len(numbers)

def get_average(student):
homework = average(student["homework"]) * 0.10
quizzes = average(student["quizzes"]) * 0.30
tests = average(student["tests"]) * 0.60
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"

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

Hi @orzagh,

Here the `get_class_average` function is calling itself ...

``results.append(get_class_average(student))``

That is a recursion, which should not be used here. You need to call the `get_average` function instead.

Ah yes, now I see! Thanks!

Its working by the way
