Why do you indent the main code in this file?  In particular, you've 
defined the lines starting at

   1.
      top = tk.Tk()
   2.
      F = tk.Frame(top)
   3.
      F.pack()

as part of the class, rather than at top-level.  Therefore the 
eWordEntryBox is a class attribute, rather than a global symbol.

I think you need to unindent those lines, so they'll be module-level code.

There are a bunch more problems with the code, starting with the fact 
that you never instantiate a Hangman instance, and continuing to missing 
self parameters on some of the methods.
