By default, the GUI is updated only at the end of each event handler.

You can change that by calling a special method on Tk, which forces it to update its GUI widgets immediately. Sadly I forgot the name of the method, but I'm sure you can find it in the documentation, now that you know what to search for. (I think it has something with "update" or "idle" or so in the name).
