I've been looking through this thread trying to see where I went wrong but haven't been able to figure it out. I'm not quite sure what the error actually means, so if you could please take a look at my code and explain what the error means/where I went wrong, I would greatly appreciate it. Thank you!

Once again, the error is: Oops, try again, get_class_average([alice]) resulted in an error: 'function' object has no attribute '**getitem**'
