In general, to avoid the start time "drift" [1], you could lock the execution with a timer e.g., to move the window from left to right *delta_x* pixels at a time every *period* ms [2]: #!/usr/bin/env python3 from time import monotonic from tkinter import Tk def timer(): return int(monotonic() * 1000) # milliseconds def call_repeatedly(period, function, *args): root.after(period - timer() % period, call_repeatedly, period, function, *args) # schedule the next call function(*args) def move(delta_x, max_x, width=200, x=[0]): root.geometry("%dx50+%d+100" % (width, x[0])) x[0] += delta_x # poor man's object if x[0] > (max_x - width): root.destroy() # exit root = Tk() period = 20 # call every *period* milliseconds delta_x = 2 # how many pixels to move at a time root.after(period - period % timer(), call_repeatedly, period, move, delta_x, root.winfo_screenwidth()) root.mainloop() [1]: http://stackoverflow.com/questions/8600161/executing-periodic-actions-in-python#comment26637231_8600301 [2]: http://stackoverflow.com/questions/24174924/how-to-run-a-function-periodically-in-python Akira -- https://mail.python.org/mailman/listinfo/python-list
