Student becomes the teacher - Part of the Whole

no error message - however everyone seems to be using a different argument in the code to get the same result… dont know why…

Please look at the last part of the code: for the function def class_average - in the exercise it clearly states the argument of that function should be “class_list” - however, everyone seems to be using “students”… can anyone explain to me why?

the course recently got upgraded to new enviroment, one of the very few small changes made was changing the name of function parameter from students to class_list, so if you find topics from before the the first of this month, its the old enviroment where `students` parameter was still used
