5. The last line is mandatory Tk programs. It loops through the code and invokes callback responses.

You left out the "in" before Tk. Also since it is so important to a new GUI programmer to understand that they are dealing with a hidden eventloop, not just some linear code, I think you should emphasize the importance of it more. Some concepts to add:

The MainLoop is tied to the Mainwindow. Kill the loop, kill the window.

Never use sleep in a gui program because it will put the loop to sleep and make the whole window unresponsive.

Other typos: but you knew knew that , Frames are very simple widgets. They are used as a type of border should be "Frames are very simple container widgets; they act as a container for other widgets";

Besides that, you switched to the grid packing manager, from pack, and don't explain it.

Uh.. my eyes are strained already. :-) The last thing I will mention, is you make no mention of the Tk "widget" program, which shows all the widgets in action.

I'm not really a human, but I play one on earth.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
