Hello,

This adds emacs-elpy to our collection, a worthy addition to Emacs when
in need of editing some Python.

To get the full experience, you'll want to install the following
(optional) additions, like:

--8<---------------cut here---------------start------------->8---
guix package -i python-jedi python-autopep8 python-yapf python-black python-flake8
--8<---------------cut here---------------end--------------->8---

You can enable Elpy by doing M-x elpy-mode in a Python buffer, and see
which tools are installed using M-x elpy-config.

Enjoy :)

Maxim
