# What is the problem with this code? it gives error like Oops, try again. get_class_average([alice]) returned 83.8666666667 instead of 91.15 as expected even though I have printed the average of alice just above and it is returning 91.15

try this for the get_class_average()

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

now you can do

``print (get_class_average(students))``
