I'd recommend giving them both a try and see what suits you best. There are loads of interactive tutorials online for both languages.
I personally found I preferred working in Ruby, so that's what I use - eg: I'm not a fan of significant indenting, I like that in Ruby you have to put 'end' (or '}') at the end of code block, I find it makes it more readable.
Also, if you're going to be doing web development, be sure to check out the available frameworks. Rails and Sinatra are the main Ruby ones, Django (and I'm sure others) for Python. Again, I found Rails works in a way that makes sense to me (probably because I came from CodeIgniter in PHP) so that helped sway me towards Ruby.
If you do go down the Ruby on Rails route, be sure to check out Why's (Poignant) Guide to Ruby and Rails for Zombies (http://railsforzombies.org)
