Hmm, why add font-lock stuff, when using display-table for dash too
would be easier and far more efficient (and you're already setting up
the display table anyway, so even simpler...)?

[I mean, like:

(add-hook 'python-mode-hook
          (lambda ()
            (unless buffer-display-table
              (setq buffer-display-table (make-display-table)))
            (aset buffer-display-table ?* [?✻])
            (aset buffer-display-table ?- [?−])))
