Not only did it work, it currently works for me. I seem to remember
bad interaction with python modes other than the one shipped with
emacs. In my .emacs I have

;; Python
;; there are several modes. Currently using
https://github.com/fgallina/python.el
;; hopefully oneday a glorious default python mode will be shipped
with emacs and we won't need this anymore.

;; (add-to-list 'load-path "~/.emacs.d/izahn")
;; (require 'python)

;; (setq
;;  python-shell-interpreter "ipython"
;;  python-shell-interpreter-args ""
;;  python-shell-prompt-regexp "In \\[[0-9]+\\]: "
;;  python-shell-prompt-output-regexp "Out\\[[0-9]+\\]: "
;;  python-shell-completion-setup-code
;;    "from IPython.core.completerlib import module_completion"
;;  python-shell-completion-module-string-code
;;    "';'.join(module_completion('''%s'''))\n"
;;  python-shell-completion-string-code
;;    "';'.join(get_ipython().Completer.all_completions('''%s'''))\n")

;; (require 'python-mode) ;;

;; python auto completion
(require 'ac-python)

All the python-mode and ipython mode stuff is commented out partly
because it did not play nice with org-mode. Using the default python
mode works for me. So, for those of you who are finding that this is
not working, what python mode are you using?

Best,
Ista
