Thanks for the comment. - What you see in the return is a list followed by an index number -- such as [a,b,c,d][2] would return c The index depends on whether n is divisible by neither, 3, 5, or both and will evaluate to 0,1,2,3 respectively -- then return the correct item from the list.

So, how did you come up with an idea like this -- that the sum of the product of two % values would give you the right index. I mostly understand what you did, I just have no idea how you would come up with this just by looking at it. A really cool approach, regardless!

Thanks for your comment . If you look at my first 2 attempts you can see some of how I got to the list idea. I guess I just saw that the output would be one of four items, then I saw if I could somehow get a number from 0 - 3 I could pick items from a list. I knew that at T/F test can also be interpreted as a 0 or 1. After a little bit of trial and error I found a way to assign a 1 or 2 to individual True responses then I saw that I could add them to get a 3. 0 is when none are true. Looking at other's code I saw a lot of one line solutions so I thought I'd give it a try. Thanks again and good luck with your coding.
