This is interesting. I completely understand your point about always calling (and using) the instance of Tk as the root. Given that, what is the point of creating a Frame object at all? I tried NOT doing it, like you said, and it seemed to work fine with my simple example. But is there a benefit to using a Frame object to group the widgets together? Or is it cleaner to just use the Tk object?
