Elpy is an Emacs package to bring powerful Python editing to Emacs. It combines a number of other packages, both written in Emacs Lisp as well as Python.

Elpy is fully documented at readthedocs.org:

http://elpy.readthedocs.org/en/latest/index.html

First, install the required Python packages::

pip install rope

Evaluate this in your *scratch* buffer:

(require 'package)
(add-to-list 'package-archives
             '("elpy" . "http://jorgenschaefer.github.io/packages/"))

Then run M-x package-refresh-contents to load the contents of the new repository, and M-x package-install RET elpy RET to install elpy.

Finally, add the following to your .emacs:

(package-initialize)
(elpy-enable)

Done.
