It looks like you're working too hard! Reversing a string doesn't require manipulating cases or splitting and reconstruction. In fact, it can be done in just one step using a slice with the proper arguments.

Also, for the 3rd item, the "capitalize" method does something different from what the instructions are asking for. But there is another string method that will do the right job.
