Maybe you can try something like the following?

    (defvar python--font-lock-keywords ...)
    (defvar python-font-lock-keywords
      '(python--apply-font-lock))
    (defun python--apply-font-lock (limit)
      (while (< (point) limit)
        (let ((next-boundary (find-next-boundary limit)))
          (if (we-should-skip-this-block)
              (goto-char next-boundary)
            (let ((font-lock-keywords python--font-lock-keywords))
              (font-lock-ensure (point) limit))))))
