Yes, that's the way to do it.

You could also use a binding on each canvas item, but I don't recommend
this.  Something like:
    def make_callback_with_id(id, real_callback):
        def callback(event):
            real_callback(event, id)
        return callback            
    ...
    def f(event, id):
        print "clicked on", id
    c = Tkinter.Canvas(...)
    item = c.create_XXX(...)
    c.tag_bind(item, "<Button-1>", make_callback_with_id(item, f)
(untested)
