Caution "self" is a convention of some importance....

See http://www.python.org/doc/2.5.2/tut/node11.html

"""Often, the first argument of a method is called self. This is nothing
more than a convention: the name self has absolutely no special meaning
to Python. (Note, however, that by not following the convention your
code may be less readable to other Python programmers, and it is also
conceivable that a class browser program might be written that relies
upon such a convention.) """

Is this in the class of things not unlike the Emacs programmer that redefines Meta-X?

$ locate py | grep py$ | xargs grep self | wc -l
340949
In ./lisp/progmodes/python.el.gz I see:

             ;; Not real keywords, but close enough to be fontified as such
             "self" "True" "False")

So you could take the hint and go with the flow or edit the .el file to read something like
this for the three not real key words.  The bytecompile it or add it to your own .emacs:

(defvar python-font-lock-keywords
  `(,(rx symbol-start
         ;; From v 2.5 reference, <A7> keywords.
         ;; def and class dealt with separately below
         (or "and" "as" "assert" "break" "continue" "del" "elif" "else"
             "except" "exec" "finally" "for" "from" "global" "if"
             "import" "in" "is" "lambda" "not" "or" "pass" "print"
             "raise" "return" "try" "while" "with" "yield"
             ;; Not real keywords, but close enough to be fontified as such
             "RubarbInTheSpringself" "RubarbInTheSpringTrue" "RubarbInTheSpringFalse")
         symbol-end)
