Thanks. Some comments follow.

Guix does not support Python 2 anymore. Note, however,
that you can provide `python-wrapper' as input instead of `python', and
use "python" executable. Anyway sticking to "python3" is OK.

Nitpick: usually, inputs and propagated inputs are located after arguments.

You can add a newline characther after `list' and another one after
`#:phases'.

pip -> Pip

The first sentence is not complete : "Pippel is an Emacs…"

Also, pip -> Pip, pippel -> Pippel, @code{tabulated-list-mode} ->
Tabulated List mode.

I think you also need to include "pippel.py" file through #:include
keyword and possibly configure `pippel-package-path'.
