  2 from Tkinter import *
  3 import sys
  4 import random
  5 class App:
  6  def __init__(self, master):
  7    frame = Frame(master)
  8    frame.pack()
  9    rotulo = Label(frame, text="Clique em 'Gerar' e boa
sorte!",borderwidth=2,bg="gray",justify=C    ENTER,relief=SUNKEN)
 10    rotulo.pack()
 11
 12    self.button = Button(frame, text="Sair", fg="red",
command=frame.quit,borderwidth=1)
 13    self.button.pack(side=LEFT)
 14    self.hi_there = Button(frame, text="Gerar Numero",
command=self.say_hi,borderwidth=1)
 15    self.hi_there.pack(side=RIGHT,padx=2,pady=2)
 16
 17  def gera_seis(self):
 18    a = {}
 19    for i in range(6):
 20       a[i] = "%02d" %  int (random.randint(0,60))
 21    resultadoA = "%s-%s-%s-%s-%s-%s" %
(str(a[0]),str(a[1]),str(a[2]),str(a[3]),str(a[4]),str(a[5]))
 22    return resultadoA
