I don't think you can go wrong with Python. I can't say one way or the other about Go.
That said; it seems to me (as just one dev's opinion in the U.S.) that Europe -- particularly northern Europe -- has a pretty healthy Clojure scene. Of course, it's not going to compare to Python/Ruby/JS in # of jobs, but if you liked it, I can tell you it only gets more fun as you learn more.
One general piece of advice -- internalize this: https://gist.github.com/jboner/2841832 (latency comparison of different operations) as one or two operations at the wrong layer will overwhelm a whole lot of algorithmic cleverness.
I would be hesitant to aim anyone's nascent development career at Clojure. Not that there's anything wrong with the language, but I think we've passed "peak Clojure":
The problem with Clojure is that I am not very proficient in JVM (actually, I know very little about it), and I know only basics (like create a simple REST CRUD), so I have some doubts that I'll end up getting job just studying language and platform in the evenings.
