if root.mainloop():
break

the Tk show up but the count don't start . plzz help

You'll have to post the Tkinter part of the code. There is no root.mainloop() in the code you posted.

ha ha fine ill put it all here

# -*- coding: cp1252 -*-

import os
from Tkinter import *
from time import *

inloged=False 
Time = 30

ended=False
first = True

#os.system("shutdown -s")


root = Tk(screenName=None, baseName=None, className='start screen', useTk=1)

userlabel = Label(root,text='username')
user = Entry(root)

passwordlab = Label(root,text='password')
password = Entry(root)

time = Label(root,text='shut-down in:' + str (Time),fg='red')


time.pack()
userlabel.pack()
user.pack()

passwordlab.pack()
password.pack()

while not inloged and not ended:   
    if root.mainloop():
        break
    sleep(1)
    print Time
    Time = Time - 1
    if Time == 0:
    #   os.system("shutdown -s")
        ended=True

You would use a StringVar and update it with the new time or whatever. The following code is an example, where the entry box and the label widget both have access to the same StringVar, so when you change the value in the entry box, the label box is automatically updated.

import Tkinter

class EntryTest:
   def __init__(self):
      self.top = Tkinter.Tk()

      self.str_1 = Tkinter.StringVar()
      label_lit = Tkinter.StringVar()

      label_1 = Tkinter.Label(self.top, textvariable = label_lit )
      label_1.pack()
      label_lit.set( "Test of Label")
    
      label_2 = Tkinter.Label(self.top, textvariable = self.str_1 )
      label_2.pack()

      entry_1 = Tkinter.Entry(self.top, textvariable=self.str_1)
      entry_1.pack()
      self.str_1.set( "Entry Initial Value" )

      cont = Tkinter.Button(self.top, text='PRINT CONTENTS',
             command=self.getit, bg='blue', fg='white' )
      cont.pack(fill=Tkinter.X, expand=1)

      exit=  Tkinter.Button(self.top, text='EXIT',
             command=self.top.quit, bg='red', fg='white' )
      exit.pack(fill=Tkinter.X, expand=1)

      entry_1.focus_set()
      self.top.mainloop()

   ##-----------------------------------------------------------------
   def getit(self) :
      print "getit: variable passed is", self.str_1.get()

##===============================================================
if "__main__" == __name__  :
   ET=EntryTest()
