[Tutor] Help with tkinter application.

Hey Arcege,
   Thanx for the reply, although it didn't quite work as you suggested, I got
the general idea. Thanx to you TKSpell is ready. Have a look below ....you
may even want to run it :) !!!
   Also Eve, thanx for trying it out, the error you mentioned:

===============================================
 python tkinter_spell.py
  File "tkinter_spell.py", line 51
    label = Label(self, text=' '.join([ x for x in self.result]))
                                            ^
SyntaxError: invalid syntax
===============================================
    most probably is because you are running python version 1.5, which does
not understand list comprehensions which are just a short cut way of doing a
particular thing to elements of a list.

Eg:
>>> l = [ "A", "B", "C" ]
>>> p = [ x.lower() for x in l ]
>>> p
['a', 'b', 'c']

       makes sense ?? if it doesn't, ask.

Anyways, here's TKSpell, for anybody who care :)

 Peace
 Steve
