Treehouse Guest TeacherAll ordered/indexed iterables can be sliced (you can't slice dicts or sets as they don't have an order/index).
Slices are, themselves, ordered and indexed.
How would you get all of the items with an even index? How would you reverse an iterable with a slice?

An even length iterable would end on an odd index. Make sure that you're starting on the correct item from the end.
