Hey tutors. Two separate submissions one day, guess I'm getting busy ;)
Anyway, I'm re-writing my hangman program to make use of my new-found
understanding of OOP, and using a GUI this time around. I decided on
coding with Tkinter, to get my feet wet with GUI stuff.
Here is the traceback:
From the logs looks like the variable is not initiated when it was used.
If I read it correct, you said it down ... that means below the line where
the error came? and if they belong to same function then this error is valid
Thanks,
Nitin

I was under the impression that when you define a function, it doesn't
try to evaluate anything yet. If I had called the function before I
defined the variable, I would understand, but I haven't. The entirety of
my (incomplete and buggy) code is now available here:

The difference is in understanding what's executed

I add a few debugging lines like that into my code, I get this:

There are quite a few errors here, one is that many of your class's
methods
don't have self as

But I was wondering (for my own
edification), can anyone point to the portion of the docs that clearly
spells out the order of execution (top to bottom, classes vs. functions,
etc.).
I found this in the tutorial in the modules section:

Very helpful, especially that last resource. Thank you!
