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.

Saving beat patterns

In the preceding iteration, we added the capability to define multiple beat patterns. However, the beat patterns can be played only on a single script run. When the program is closed and restarted, all previous pattern data is lost.

We need a way to persist or store the beat patterns beyond a single program run. We need the ability to store values in some form of file storage and reload, play, and even edit the patterns. We need some form of object persistence.

Python provides several modules for object persistence. The module that we will use for persistence is called the pickle module.

Pickle is a standard library of Python.

An object represented as a string of bytes is called a pickle in Python. Pickling, also known as object serialization, lets us convert our object into a string of bytes. The process of reconstructing the object back from the string of bytes is called unpickling or deserialization.

More information about the pickle module is available at http://docs...
