from Tkinter import *

class MyApp(Tk):

     def __init__(self):
         Tk.__init__(self, className='MyApp')
         self.after(1000, self.label_timeout)
         # add whatever initialization you may need

     def label_timeout(self):
         # change label contents here
         self.after(1000, self.timeout)

myapp = MyApp()
myapp.protocol('WM_DELETE_WINDOW', on_close)
myapp.mainloop()
