Yes thats correct. You had to pick third party libraries for these types of things, which wasn't that big of a deal since the community did a good job of rallying around good libraries. There's nothing like ruby/rails (I love me some rspec!), but ultimately it came down to lang pref for me, and maybe performance (dev reload cycle mostly). Plus, python has a lot of very interesting stuff in machine learning and science.
