Untested, but try this :
#+name: localize
#+BEGIN_SRC emacs-lisp :var file="" srcinfo=(org-babel-get-src-block-info)
(let* ((dir (cdr (assoc :dir (nth 2 srcinfo))))
(rfile (concat (file-name-as-directory dir) file))
(lfile (car (last (split-string rfile ":")))))
(copy-file rfile lfile 1)
lfile)
#+END_SRC
then use
#+HEADER: :post localize(*this*)
in your python src block.
