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.

In this iteration, we will code the features marked in the following screenshot:

This includes the play/stop, pause/unpause, next track, previous track, fast forward, rewind, volume change, and mute/unmute features.

Adding the play/stop function

Now that we have a playlist and a Player class that can play audio, playing audio is simply about updating the current track index and calling the play method.

Accordingly, let's add an attribute, as follows (see code

current_track_index = 0

Furthermore, the Play button should act as a toggle between the play and stop functions. The Python itertools module provides the cycle method, which is a very convenient way to toggle between two or more values.

Accordingly, import the itertools module and define a new attribute, as follows (see code

toggle_play_stop = itertools.cycle(["play","stop"])

Now, every time we call next(toggle_play_stop), the value returned toggles between the play and...
