I'd be lazy and just use the :post argument.  So something like the
following.  I'm pretty sure I once wrote a :post function that took
negative number (to add a final hline), but I couldn't find it...

    #+BEGIN_SRC python :post add-hline(tbl=*this*)
    return([ ["a"], [1], [2]])
    #+END_SRC

    #+RESULTS:
    |---|
    | a |
    |---|
    | 1 |
    | 2 |

    #+name: add-hline
    #+BEGIN_SRC emacs-lisp :var tbl='((a) (b) (c)) hlines='(0 1)
      (loop for hline in
            (mapcar* '+ hlines 
                     (number-sequence 0 (length hlines)))
            do (setq tbl (append (subseq tbl 0 hline)
                                 '(hline)
                                 (subseq tbl hline))))
    tbl
    #+END_SRC

Hope it helps,
Rasmus
