Tkinter is event-driven, and you need to keep the event loop running to 
make sure that changes to the widgets makes it to the screen.

Usually, this is handled by the "mainloop" function, but if you're 
spending considerable time at the Python level, you need to call the 
"update" or "update_idletasks" methods from time to time to give Tkinter 
a chance to process incoming events.  In your case, you can simply call 
the method after you've modified the label:

     label.config(text="something")
     label.update()

Hope this helps!
