See title.

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

here:

``class_list = [lloyd, alice, tyler]``

class_list should be named `students`, like you named in an earlier exercise, otherwise you get in trouble in the next exercise

Just curious, where do you think you defined `student`? So i can correct where you are going wrong

now you have to change your for loop, this change also means you know loop over your function parameter of get_class_average function, this means you can know calculate the class average for a class of any size (1, 2 or 3 students)
