As exciting as it may be to see that first GUI window pop up on the screen, "Hello World" is not a terribly interesting application. Let's start again and dig a little deeper into Tkinter as we build a slightly larger program. Since the next chapter will see you landing a job at a fictitious agricultural laboratory studying fruit plants, let's create a little program to gauge your opinions about bananas.
