For this unit, work through the following preparatory activities.

• The first three sections of An Introduction to Tkinter:

  • “What’s Tkinter”
  • “Hello, Tkinter” — Notes:
    • The examples use events; this is the basis for event-driven programming.
    • You should import the TkInter library using from tkinter import *, with a small “t”, rather than the capitalized version they give in their example.
  • “Hello, Again”

  It’s also worth noting the list of interface tools, known as widgets listed under the “Tkinter Classes” section and then again individually under “Part II”. This listing, called an Application Programmers Interface (API), includes detailed descriptions of what the widgets do and how to use them.

  When finished, try to use the sample code in the third section to build a simple interface that looks as follows. The “Quit” button should, of course, terminate the program.

  

• This video demo — key ideas not emphasized in the text:
  • Usability
  • Event-driven programming
