I can't even begin to undeerstand what you're trying to do here: 
<KeyPress-space> is only valid in a string as an event description that you can 
pass to the various bind methods, so converting it to an int has no meaning at 
all for me...

Maybe you should begin with a tutorial for Tkinter; you'd surely understand 
better what's going on and how you can do things with it. "Thinking in Tkinter" 
is usually a good place to start:

(follow the link all_programs.html to get the full the whole series of scripts 
and the explanations around them).
