Overview of this book

Tkinter is the built-in GUI package that comes with standard Python distributions. It is a cross-platform package, which means you build once and deploy everywhere. It is simple to use and intuitive in nature, making it suitable for programmers and non-programmers alike. This book will help you master the art of GUI programming. It delivers the bigger picture of GUI programming by building real-world, productive, and fun applications such as a text editor, drum machine, game of chess, media player, drawing application, chat application, screen saver, port scanner, and many more. In every project, you will build on the skills acquired in the previous project and gain more expertise. You will learn to write multithreaded programs, network programs, database driven programs and more. You will also get to know the modern best practices involved in writing GUI apps. With its rich source of sample code, you can build upon the knowledge gained with this book and use it in your own projects in the discipline of your choice.

Importing Tkinter

This section describes the different styles of importing Tkinter modules. In the preceding example, we imported Tkinter by using the following command:

from tkinter import *

This method of importing eases the handling of methods defined in the module. That is to say, you can simply access the methods directly. Generally, it is considered bad practice to import all (*) the methods of a module like we did here. This is so because this style of importing leads to memory flooding, namespace confusion, and difficulty in bug tracking and/or reviewing code. Importing into the global namespace can also lead to an accidental overwriting of methods from other libraries in the global namespace.

There are several ways to import Tkinter in which this overlapping can be avoided, with a common way being the following one:

import tkinter

This style of importing does not pollute the namespace with a list of all the methods defined within Tkinter. However, every method within Tkinter will now have to be called by using the tkinter.some_method format instead of directly calling the method.

Another commonly used import style is as follows:

import tkinter as tk

Here too, you do not pollute the current namespace with all the Tkinter methods. Now, you can access methods such as tk.some_method. The tk alias is convenient and easy to type. It is commonly used by many developers to import Tkinter.
