Root. Geometry (" 250 x150 ")

Val=StringVar ()
L1=Label (root, textvariable=val)
L1. Pack ()
Val=val. Set ("...
")

L2=Label (root, text="PPP")
L2. Pack ()

For a in range (10000) :
I=STR (a)
# val=val. The set (" 8888 ")
L2. Config (text=I)
A +=1
Time. Sleep (0.1)

Root. Mainloop ()

Simple can have a Timer Timer

 
The from tkinter import * 
The import time 
The from threading import Timer 

Root=Tk () 
Root. Geometry (" 250 x150 ") 

Val=StringVar () 
L1=Label (root, textvariable=val) 
L1. Pack () 
Val=val. Set ("... 
 ")

L2=Label (root, text="PPP") 
L2. Pack () 

A=0 
Def set_text () : 
Global a 
L2. Config (text=STR (a)) 
A +=1 
If a & lt; 10000: 
T=the Timer (0.1, set_text) 
T.s tart () 

T=the Timer (0.1, set_text) 
T.s tart () 

# for a in range (10000) : 
# I=STR (a) 
# # val=val. The set (" 8888 ") 
# l2. Config (text=I) 
A +=# 1 
# time. Sleep (0.1) 

Root. Mainloop ()
