python

1. In an object-oriented Tkinter application (i.e., one in which we implemented the user interface as a class), why did we use bound methods when we set up our event handlers?

2. Suppose that bound methods didn't exist in Python, so that we couldn't have solved the problem that way. Using only techniques that have been taught in this course to date, suggest another way that we could have set up our event handlers, assuming that our design otherwise wasn't going to change (i.e., we're still implementing our user interface as a class, with an object of that class representing a running instance of that user interface). Demonstrate your chosen technique with a short example. There's no need to write an entire program; show us enough code for us to understand the technique, but focus some effort on eliminating things that aren't necessary to convey your idea
