;; Contains all the default values from:
;; https://github.com/python-lsp/python-lsp-server/blob/develop/pylsp/config/schema.json
;; Works on GNU Emacs 27.1 
;; (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.23, cairo version 1.16.0) of 2021-01-18, modified by Debian
;; From looking at the server output, some plugins support additional options.
