say_hello Line-by-Line

In the last entry about the guided introduction to Python and Tkinter, we saw a self-contained function that creates and populates a Tkinter frame. In the next step, we look at that code line-by-line. Some important take-aways in this section of code are how to manage the dimensions of the frame and how to ensure the frame is echoed to the screen, instead of dwelling inaccessibly in the computer's Twilight Zone. See "Say Hello - Part Two" for a complete discussion on each line of the say_hello method.
