Oops, try again. get_class_average([alice]) resulted in an error: global name 'student' is not defined

This global variable that stores all the dictionary was suposed to be called students and not,

that way here,

you would iterate through all the dictionaries just by saying,

`for student in students: #This way is also better for readability`

and in doing so that would mean this line would have to be modified,

to,

`results.append(get_average(student))`

All in all if you get the indentation correct,

``````for x in example:
example.append(something)
return something(example)``````

it should work.
