#41310 — What am I doing wrong in this simple tkinter example?

Hi all, I'm well into "Python Programming for the Absolute Beginner" in order to 
become more acquainted with the language.  However, when I got to page 304 and 
did my first example:

http://bin.cakephp.org/view/1107093008

And this is the error that I'm getting:

http://bin.cakephp.org/view/399711843

This is the code that came with the book:

http://bin.cakephp.org/view/514822432


What I don't understand is, why am I getting that error?  I've done diff -w
and the code looks for the most part the same.  What am I doing wrong when I
put the application together?

    self.secret_txt.delete(0.0, END)
    self.secret_txt.delete(0.0, message)

Is the second one supposed to be adding text? I'm not familiar with
tkinter but that's the line with the error, and it looks a little odd.

Think about it. "delete" is not going to add text. You want "insert" 
instead.

The error is that indexes are supposed to be integers, instead you have
a text string:

"That's not the correct password, so I can't s hare the secret with you."

In the example that I have posted from the book it works just fine.  I also used 
this batch file to help me along.

longevity.py

Hence the question mark over my head at the moment :) .

Yep, I just checked the book's version again and the difference is
clear. Check out the two lines I quoted in my previous post, and look
at the corresponding two lines in the book's version. You should see
the difference. :)

By the way, I like the choice of secret. It lends itself well to a
discussion of recursion - how do you live to 99? Live to 98, then be
careful. Etcetera. You need just one special case: How do you live to
1? Be born, then be careful. And there you have it, a perfect problem
for defining recursion vs iteration, as both can do the job!

Glad to be of service. Welcome to a life of programming, where the
palm meets the face on a regular basis... more frequently if you use
Microsoft Windows, tar, non-eight-bit-clean transmission methods, or
Adobe products, and extremely common as soon as you take over someone
else's code [1], but inevitable even without these stimuli. :)

Have fun!

A pretty funny example of this is depicted in the fine film
Office Space.

You are giving a message to the delete call, but delete call
needs an integer to work. In the book, it's not a delete call
but an insert call that's why it works there.
