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.
