Python GUI Programming Cookbook, Second Edition - Second Edition

Overview of this book

Python is a multi-domain, interpreted programming language. It is a widely used general-purpose, high-level programming language. It is often used as a scripting language because of its forgiving syntax and compatibility with a wide variety of different eco-systems. Python GUI Programming Cookbook follows a task-based approach to help you create beautiful and very effective GUIs with the least amount of code necessary. This book will guide you through the very basics of creating a fully functional GUI in Python with only a few lines of code. Each and every recipe adds more widgets to the GUIs we are creating. While the cookbook recipes all stand on their own, there is a common theme running through all of them. As our GUIs keep expanding, using more and more widgets, we start to talk to networks, databases, and graphical libraries that greatly enhance our GUI’s functionality. This book is what you need to expand your knowledge on the subject of GUIs, and make sure you’re not missing out in the long run.

Creating self-testing code using Python's __main__ section

Python comes with a very nice feature that enables each module to self-test. Making use of this feature is a great way of making sure that the changes to our code do not break the existing code and, additionally, the __main__ self-testing section can serve as documentation for how each module works.


After a few months or years, we sometimes forget what our code is doing, so having an explanation written in the code itself is indeed of great benefit.

It is a good idea to always add a self-testing section to every Python module, when possible. It is sometimes not possible but, in most modules, it is possible to do so.

Getting ready

We will extend the previous recipe, so in order to understand what the code in this recipe is doing, we have to first read and understand the code of the previous recipe.

How to do it…

First, we will explore the power of the Python __main__ self-testing section by adding this self-testing section to our LanguageResources...
