For a console app you could use a for-loop with time.sleep() or
http://docs.python.org/dev/py3k/library/sched.html

For a script that uses tkinter there's the after() method.
Example:

root = Tk()

def hi():
    print("ho")

def hi_reschedule():
    hi()
    # make tkinter call it again after 1000 milliseconds
    root.after(1000, hi_reschedule) 

hi_reschedule() # call it manually the first time
