How to customize emacs in python mode to highlight operators? -

i'm setting emacs python ide, , i've found plenty of material online explain auto-completion, among variety of other features. can't figure out, though, how syntax highlighter highlighting magic on operators.

how can customize emacs in python mode make + - different colors? i'd make integers, floats, , parentheses different colors well.

i have setup programming modes. defines 2 separate faces, 1 operators , 1 "end statement" symbol (not useful in python, obviously). can modify "\\([][|!.+=&/%*,<>(){}:^~-]+\\)" regex match operators interested in , customize faces color want.

(defvar font-lock-operator-face 'font-lock-operator-face)  (defface font-lock-operator-face   '((((type tty) (class color)) nil)     (((class color) (background light))      (:foreground "dark red"))     (t nil))   "used operators."   :group 'font-lock-faces)  (defvar font-lock-end-statement-face 'font-lock-end-statement-face)  (defface font-lock-end-statement-face   '((((type tty) (class color)) nil)     (((class color) (background light))      (:foreground "darkslateblue"))     (t nil))   "used end statement symbols."   :group 'font-lock-faces)  (defvar font-lock-operator-keywords   '(("\\([][|!.+=&/%*,<>(){}:^~-]+\\)" 1 font-lock-operator-face)     (";" 0 font-lock-end-statement-face))) 

then, enable adding hook relevant modes (this example assumes using "python-mode"):

(add-hook 'python-mode-hook                   '(lambda ()                      (font-lock-add-keywords nil font-lock-operator-keywords t))                   t t)
