Welcome to Tkinter GUI Programming by Example. We will be exploring how to use the Tkinter library, which is included alongside most Python installs. This framework is very simple to use, and has a powerful event-handling system and an open license, perfect for anyone who wishes to quickly write and share graphical applications.

Throughout this book, we will be creating three powerful desktop applications, learning about the variety of widgets available in Tkinter. After we have these applications polished, we will then learn how to share them with other people by packaging them up for sharing. When you have finished this book, you will have in-depth knowledge of Tkinter, its widgets, GUI-design principles, and packaging Python projects.
