  1. class is a keyword in Python and it should not be used as a variable name.
  2. Function get_class_average takes one argument - students, you should use it in the for loop:

for student in students:

hi
what is rong here?

def get_class_average(students):
    results=[] 
    for student in students:
        results.append(get_average(student))
    return average(results)

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


#4

Python is not able to find the average function. Can you post your whole code?

In this exercise -> https://www.codecademy.com/en/courses/python-beginner-en-qzsCL/1/1, you have written function called average, you should add it to your code.
