Error when code returns the expected response..."student becomes the teacher"


#1

I get "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" error when my code returns the expected response... can someone please help identify what is missing here?

#!/usr/bin/python

    elif score >= 60.0 :

Hi @microrunner63600 ,

In Exercise 3: Put It Together, you needed to write the following line of code ...

students = [lloyd, alice, tyler]

... but it is missing from the code that you have posted.
