It's not easy to restart the REPL.  You can send "quit()" to it and
invoke run-python again interactively by typing out one command after
another, but if you write a procedure such as this one below, it doesn't
work: it gives me the impression that there's a timing issue, that is,
perhaps the procedure is too fast and something happens before it
should.

(defun python-save-send-buffer-to-repl ()
  (interactive)
  (save-buffer)
  (python-shell-send-string "quit()")
  (run-python)
  (python-shell-send-buffer)
  (python-shell-switch-to-shell))
