** Python coding
Here, the focus is on three ways to extend Emacs's built-in ~python-mode~ out of
the options listed on the [[https://www.emacswiki.org/emacs/PythonProgrammingInEmacs][Python Programming in Emacs]] wiki page:
The [[https://www.emacswiki.org/emacs/PythonProgrammingInEmacs][Python Programming in Emacs]] wiki page lists options to enhance Emacs's
built-in ~python-mode~. Here, the focus is on two packages:
1. [[https://github.com/pythonic-emacs/anaconda-mode][Anaconda - code navigation, documentation lookup, and completion for Python]].
2. [[https://github.com/joaotavora/eglot][Eglot - Emacs polyGLOT: an Emacs LSP client that stays out of your way]]. The
maintainer also contributes to Emacs itself and has a deep understanding of
[[https://sheer.tj/the_way_of_emacs.html][the Way of Emacs]]. He refuses to add new features without seeing how they fit
into [[https://sheer.tj/the_way_of_emacs.html][the Way of Emacs]] as this discussion at [[https://github.com/joaotavora/eglot/issues/523][Eglot github issue: org-mode
source code blocks]] shows.

The snippet below initializes [[https://github.com/pythonic-emacs/anaconda-mode][anaconda]]. See [[https://github.com/jorgenschaefer/elpy/blob/8d0de310d41ebf06b22321a8534546447456870c/elpy.el#L2775][elpy-module-company]] for how to
handle ~company-backends~ as a local variable and the call to ~advice~ opens
Python org-mode edit-buffers in ~anaconda-mode~.
