Unfortunately, I didn't work on this one locally (Couldn't be bothered to set up the local tests with this one), so I don't have the same collections of attempts.

I am respecting the conditions of the notes section. I can see that the message has changed. My living_room function has logic which depends only on prisoner_number, lightbulb, and previous_visits. I do not have code outside of the living room function, and I haven't introduced any additional data structures. Update: I managed to pass after shuffling around the logic.

I am getting the error: "living_room should be the only name in the global scope, and it should not have a state," but I haven't added any additional variables to the code, inside or outside of living_room.
Can someone give me a hint as to what this might mean?
