Does Tk do some extra work that a simple call to Frame won't do? More specifically, what is the benefit of doing: root = tk.Tk() app = Application(master=root) app.mainloop() as opposed to: app = Application() app.mainloop() Also, in the first example, what is the difference between calling app.mainloop() and root.mainloop()? They both seemed to work when I ran them.
