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

lloyd = {

This is a reference object that is meant to be in global scope. The items are themselves reference pointers so should not be written as strings.

#3

meaning? students = [ lloyd, alice, tyler]
it still kicks out the same error

thanks for the help its been most frustrating

#5

Yes. Write that up with you other data dictionaries.

#6

This should be `student` so only one data object is passed in.
