I tried this:

(add-hook
 'python-mode-hook
 (lambda ()
   (font-lock-add-keywords
    nil
    '(("\\(\\(?:\\sw\\|\\s_\\|\\.\\)+\\)("
       1 font-lock-function-name-face nil)))))

I'm not sure it's exactly the same thing you're trying to do, but
underscores didn't pose any problems for highlighting the full symbol.
Perhaps your regular expressions just isn't quite right.
