This is what the box that pops up said:
"Oops, try again. One of the following is missing or broken when we tried to use it: alice, lloyd, tyler, students, getclass_average, get_letter_grade_"
The box where the code comes in says this:
"Traceback (most recent call last):
File "python", line 47, in
TypeError: 'function' object has no attribute 'getitem'"

Hi this line

print get_class_average[lloyd, alice, tyler]

it's the call function so it should be like that

print get_class_average([lloyd, alice, tyler])

the same for this line

print get_letter_grade
