Binary package “python-mode” in ubuntu bionic

Python mode for GNU Emacs and XEmacs

 Provides a major mode for GNU Emacs and XEmacs to edit, debug, and develop
 Python programs and doctests.
 .
 If you install this with XEmacs 21, it will replace the included
 python-mode.el, which may or may not be a more recent version
 (use "C-h v py-version" to compare).
 .
 Since this package automagically loads after Python mode shipped with
 GNU emacs >= 22, installation of this package makes python-mode's
 mode the default for editing Python code in emacs.
