Oops, try again. One of the following is missing or broken when we tried to use it: alice, lloyd, tyler, students, get_class_average, get_letter_grade

Why is this throwing this message?

``Replace this line with your code.``

#2

the `students` list you build in 4. put it together is missing

#3

what do you mean by this?

#4

in exercise 4 of students becomes teacher you build a list, this list is required to pass this exercise. If you have a question, please make your own topic, this topic is for helping mayuri.rajput

#5

if I'm not mistaken, you cannot create a new list as an argument. you haven't assigned a value to it, therefore it won't work. you need to create the list before.

#6

you can pass a new list as argument:

``get_class_average([lloyd, alice, tyler])``

but the exercise requires you to have the list stored in a variable called students
