[Tkinter-discuss] strange bind problem...

[Martin Franklin]

Hi All,



Hope you can help I have written a quick HangMan game for my 6
year old son - not me ;-)

And it works great..... but when the word changes, after guessing
all the right letters, I get an extra 'guess' at the start of the next
word.  I guess you would have to run it to see what I mean...

Sorry it's a bit long


 from Tkinter import *
 from string import letters, lowercase

FONT = "Courier 36 bold"


class HangMan(Tk):
     def __init__(self):

         self.bind("<Any-Key>", self.binder)

             "royal", "cowboy", "enjoy", "annoy", "voyage"]
         random.shuffle(self.words)

         f = Frame(self)

         self.canvas = Canvas(f, background = "white", width = 300,

Hope you can help,
