For what it's worth, several universities have chosen Python to teach introductory CS rather than Lisp/Scheme. Also NASA, Industrial Light and Magic, Disney, etc have chosen Python. But as others have pointed out, try out both and see which one feels more "natural" to you.  For me, Python was like "executable pseudo code" and I found I could grok the batteries included libraries much better than anything that Ruby had to offer at the time (about v2.1 vintage).
