# 8/9 Getting an error though code is correct and prints correctly

#1

Code should be spitting out the averages for each student in the class. It does this, however I keep getting an error message saying “get_class_average([alice]) should return a number.” I’m pretty sure my code is returning numbers…not sure why it’s just Alice that isn’t. Any thoughts?

``````

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]
}

# my code
def average(numbers):
total = sum(numbers)
total = float(total)

def average(numbers):
total = sum(numbers)
total = float(total)/len(numbers)

def get_average(student):
homework =average(student['homework'])
quizzes =average(student['quizzes'])
tests =average(student['tests'])

weight = homework*0.1 + quizzes*0.3 + tests*.6
return weight

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

classy = [lloyd, alice, tyler]
print get_class_average(classy)

You are returning a list. The list contains all the weighted averages, but the return should be the average of those.

``return sum(results) / len(results)``
