Since I have contributed quite some code for Python code completion in
Emacs, I feel a bit concerned by this question, so let me say a few
things about the current state of completion.

It's been two years ago when I contributed my completion code, but
still, it is quite hard to get a working Emacs-Python-Environment
having code completion. I think that a novice (or non-expert) user will
have problems getting it working. Theoretically it could be quite easy,
just create a ~/.emacs.d/init.el file with the following contents:

(require 'pymacs)
(setq py-load-pymacs-p t)
(require 'auto-complete-config)
(ac-config-default)

This is for code completing with an auto-complete pop-up-menu. If you
prefer a less obtrusive completion using only the TAB key (as I do),
then use these lines:

(require 'pymacs)
(setq py-load-pymacs-p t)
(setq py-complete-function 'py-complete-completion-at-point)
(setq py-complete-set-keymap-p t)

So far so good. However, the problem is, that you must have at least
pymacs 0.25, which is unfortunately not part of Ubuntu 14.04 (to name a
popular distribution). In this case, you'll have to get pymacs 0.25 (and
emacsen-common) from the upcoming Ubuntu 14.10. So with a standard
Ubuntu 14.04 LTS installation, it will not work. Let's hope that things
improve with Ubuntu 14.10, then users will at least have all
preconditions for a working code completion.

However, I think that it will be still too hard for the normal user to
make it work. Why not have a simple configuration option, which will
allow users to enable code completion by a simple mouse click? Such a
function should set up all variables and check if the required packages
are available and warn the user if not. I must admit that I do not use
the Emacs package management (ELPA), I would rather rely on the
packages of my Linux distribution, but maybe ELPA could be helpful to
get all those prerequisites.

Regards,
Urs
