That is easy - whatever the mechanism that binds the shortcut does, it is passing an extra parameter to your reset method.

Since you don't care what it is at all, just declare your method to accept an extra optional parameter, and you should be good:

...
def reset(self, event=None):
    self._game.get_default_score()
    ...

So, searching for "bind_all" we find out your code actually uses tkinter, and what tkinter passe along to your method is the "event" - an object with information on what key whas actually pressed and such - http://effbot.org/tkinterbook/tkinter-events-and-bindings.htm
