IMHO it is more important that you can reason why you chose a language as your Happiness/Hacking/Bread-n-Butter languange, than which language you chose. I think it's perfectly valid to have a language in more than one category.
Hacking: Python, because I know python really well, it has a very complete set of libraries and when all is said and done, for most tasks, I'll simply finish it faster in python than in any other language.
BnB: Python, because my last two jobs have been working on python apps. But also more and more javascript as we are moving some of our stuff to webapps.
