I just ran into this.  I'm no Tkinter or Python expert, but here's what I

If you're typing this in interactively, add the following after the
mainloop() call:

This doesn't seem to work if you run a script non-interactively - it seems
that it gets destroyed automatically.  Garbage collection, I guess.

To avoid namespace pollution, my personal style (for the examples I've done)
is to do this:
import Tkinter
tk = Tkinter
root = tk.Tk()
button = tk.Button( etc. )

Have fun.


PS As a doctor, you should know the value of sleep.  I hope you're getting a

PPS That has got to be one of the most hippocritical remarks I've ever made.
PPPS I'm sorry.
PPPPS I'll shut up and go to bed now.  Hopefully I can sleep.
