Here, the window is built with its contents, but the application is not started until you've done a top.mainloop() (or just mainloop()). This is required to be able to treat user requests. Until then, the window may actually not show up (depends on the platform, in fact). > time.sleep(5) Now you wait for 5 seconds, but the application is still not started. > print "script finished" > mainloop() Now the application starts and begins to treat user requests. What are you trying to do exactly? If you just want to automatically quit the application after 5 seconds, here is a way to do it (untested): -------------------------------------------- ## The script starts exactly as yours do from Tkinter import * print "script started" top = Tk() F = Frame(top) F.pack() Hello = Label(F, text="hello world") Hello.pack() ## Now, we'll register an event to call top.quit ## after 5 seconds (= 5000 milliseconds) top.after(5000, top.quit) ## Now we start the main loop top.mainloop() ## This should happen after top.quit() is ## executed by the event registered via after print "script finished" -------------------------------------------- HTH -- python -c "print ''.join([chr(154 - ord(c)) for c in 'U(17zX(%,5.zmz5(17;8(%,5.Z65\'*9--56l7+-'])" -- http://mail.python.org/mailman/listinfo/python-list
