Hello Mic,

Its usually better to paste long programs into a pastebin web site and

This saves cluttering up people mail with long messages, and also the
pastebin rendering will usually be easier to read with syntax coloring etc.

Please keep a attribution line when quoting people directly. Even something simple like "Fred wrote" will do.


Alright. Sorry if I should know this, but what is a pastebin web site and how do
I paste my program into a pastebin web site?

Here's one: http://pastebin.com/

But as I've just written in another post, please don't use it :)


While its perfectly legal Python to create a class inside a method its
very unusual in practice and very restricting in the use of the class.
Its nearly always better to declare all your classes at the top level of
the program.

Why is it restricting?


Because generally speaking, if you define a class inside a function (or method), you can't use it *except* inside that function or method.

class K:
    def method(self, x):
        class Q:
            pass

instance = Q()


This doesn't work because Q is not visible from the outside of K.method. Sometimes this is what you want; generally it is not.


I don't know much about tkinter, so I will avoid commenting about your code.
