19,870 PointsSounds like you didn't handle enough test cases in jupyter.
Your code correctly returns [5, 3, 1] for a list with an odd number of items [1, 2, 3, 4, 5].
If you try testing a list with an even numbers like [1, 2, 3, 4, 5, 6] you'll get back the incorrect [6, 4, 2] because you are starting at the end and stepping -2. So you get back the odd ones.
You need to specify the correct starting point (the challenging part) - just ask if you need additional guidance.
