RE: Automatically enable python mode

[Doug Lewan]

Olive,

The variable `interpreter-mode-alist' is what you want.

This worked for me to get Python2 recognized.

        (setq interpreter-mode-alist (add-to-list 'interpreter-mode-alist (cons 
"python2" 'python-mode)))

This can be found in the emacs *info* documentation at `Choosing Modes'.

I hope this helps.

,Doug
