How to tell Emacs/TRAMP to use the local shell, instead the shell of remote machine?

Question

I have the following function defined in my dot-Emacs:

(defun call-shell-refresh-browser ()
  ;; When pressing 'sf', save the content and refresh the browser
  (interactive)
    (save-buffer)
    (shell-command "python ~/Dropbox/Sys/Linux/chrome-refresh-back-emacs.py")))

It saves the buffer in Emacs, then switching to Chrome, reload the webpage and gets back to Emacs. This worked like a charm.

Until now, I use TRAMP to edit files on a remote machine. When I save it, and call the function call-shell-refresh-browser, it looks in the remote shell for the script chrome-refresh-back-emacs.py which don't exists on the remote machine.

How could I tell Emacs/Tramp to switch to the local shell on my machine, when editing a remote file? This is without terminating the current TRAMP session.

You must change default-directory to be a local file name. Like this:

(let ((default-directory temporary-file-directory))
  (shell-command "python ~/Dropbox/Sys/Linux/chrome-refresh-back-emacs.py"))
