Now, how did I know you were going to want to do that? From python-mode.el (for font-locking):

 ;; pseudo-keywords
 '("\\b\\(self\\|None\\|True\\|False\\|Ellipsis\\)\\b"

I swear I filled the time machine's tank when I was done with it.

Ellipsis then? It's probably used /much/ less than None, but still.
