Hi Bill,

Emacs and XEmacs are programmed in a variant of the Lisp language, and if
you ever feel curious about how python-mode works, we can always look at
the 'python-mode.el' file.

Here the chunk of emacs lisp code that's relevant to your question:



;;;;;; within the 'python-mode.el' emacs lisp file:

(defcustom py-python-command "python"
  "*Shell command used to start Python interpreter."
  :type 'string
  :group 'python)

(defcustom py-jpython-command "jpython"
  "*Shell command used to start the JPython interpreter."
  :type 'string
  :group 'python
  :tag "JPython Command")

;;;;;;


These two variables are used to execute Python's shell.



If we want to change the python executable that xemacs calls when we emacs
commands like 'C-c C-!', we can set the following in our personal '.emacs'
configuration file:

;;;
(setq py-python-command "python2")
;;;



Hope this helps!
