Python does have the strength in all the powerful libraries it makes available to you, and that may be a determining factor in the relative popularity of Python v. Ruby in the future.

I've used Python for many years but recently took a serious look at Ruby to see what it has. I haven't looked back - I found Ruby to be less verbose and still easy to read, and very enjoyable to code in. Python was enjoyable too, but for me, Ruby much more so.
