#code1
from Tkinter import *
class Application(Frame):

Frame.__init__(self, master)
self.grid()
self.createWidgets()

self.grid()
self.createWidgets()

root.mainloop()
#code3
from Tkinter import *
class Application(Frame):
def __init__(self, master=None):
Frame.__init__(self, master)
self.grid()
self.createWidgets()
def createWidgets(self):
self.quitButton = Button ( self, text='Quit',
command=self.quit )
self.quitButton.grid()
app = Application()
app.master.title("Sample application")
mainloop()
code1,code2.code3 all can run ,
what's the difference between mainloop and app.mainloop and root.mainloop?
do they have different meaning?which one is right in code1,code2,code3??_______________________________________________
