Hi Jason,

That was a nice idea but sadly, reversed doesn't return a string, it returns an iterator object.

To transform your iterator back to a string, the simplest thing to do is use join() to turn the sequence into a string. Once you've successfully wrangled your iterator back into a string, you will have the correct value.

Good luck!

Alex
