Python (though not by any means a functional language), offers many functional programming constructs like map, filter, zip etc. If you want to transition slowly into "thinking" in a functional language, I suggest you can get started on that path with Python. If you want to take the jump straightaway - I will suggest going for Erlang. Erlang has plenty of nice web libraries like mochiweb, nitrogen etc. using which you can actually write a web based product.
