# Student Becomes Teacher: 9/9 Correct Output, But Still an Error?

#1

## B 8.55 B

BUT still there is an error message saying: “One of the following is missing or broken when we tried to use it: alice, lloyd, tyler, students, get_class_average, get_letter_grade”

``````

lloyd = {
"name": "Lloyd",

"quizzes": [88.0, 40.0, 94.0],

"homework": [100.0, 92.0, 98.0, 100.0],
"quizzes": [82.0, 83.0, 91.0],

}

for student in students:
results.append(get_average(student))
return average(results)

print getclassaverage([lloyd, alice, tyler])

Can someone PLEASE double check the code and find what has to be added/removed

The lesson wants us to use underscores ( `_` ) with our function names, so basically, review how your function names are spelled compared to how the lesson wants them spelled.

Also, reread the 1st instruction, we need to use `students` as our argument, but I don’t see where you defined `students` anywhere.

#3

So I have added students and added the proper underscores according to the lesson’s guidelines, but yet another error has now occured:

#4

That error means your code is unindented and it should match the same indentation level as some of your code, how do we fix that?

But, screenshots make it hard for me to be able to help you.

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

Seems that it has been fixed now that I tried tinkering with it again.
