I do agree with shooter that python is good technologically... but the problem with Python web frameworks is that there's no one official framework yet for python that's overwhelmingly popular in the python world (though someone can prove me wrong). The end result is that there aren't that many books on stuff like Django (compared to other technologies), which really sucks when you're just starting out.
Rails on the other hand has tons and tons of books. I just started a little less than a year ago and I've caught up fast because of the plethora of books and communities for Rails.
in the end, if you happen to find your partner quick - they may help you choose (that's probably the best route)
Forgot to mention - check out some video tutorials of Rails programming:
http://peepcode.com (not free but really really good - they actually have 2 vids that covers all of the basics of Rails - in I think about 3-5 hours; you're not goign to remember all of it in the 1st run but it gets u comfy)
