Use a lambda:

foo = lambda s="sure?" : # define it here
q = Button(text="Quit"), command=foo)

Alternatively you can use the bind mechanism which passes an 
event object to your handler - but the event might not hold 
what you need...

Thirdly you can make your handler a method of a class and 
have the class store the 'parameters'.
