Go to Options. Near the bottom, it will say "Edit Init.File" Click on it.
Make an entry on a separate line near the top as follows (require 'python-mode) Then save the init file. When you open files with a .py extension xemacs should automatically go into "python mode" If you read the init.el file it will teach you a little about how to configure it. If you don't care about that and only want a python editor, then just add the line above. rpd -- http://mail.python.org/mailman/listinfo/python-list
