A smallish Tkinter question

"""
What I want: A little window to open with a 0 in it. Every second, the
0 should increment by 1.
What I get: A one second delay, see the window with a 1 in it, and then
nothing appears to happen. Never see the 0, never see a 2.  Any quick
clues? Thanks. Nick. (Python 2.4, Win98).

***Many*** thanks. I was getting right confused, but this is pretty
clear. I had also tried, in run(...):
  while True:
  sleep(1.0)
  ...

But it's clear from your response why this also didn't work!

Nick.
