Python GUI Programming Cookbook, Second Edition - Second Edition

By: Burkhard Meier

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.

Using __init__ to connect modules

When we create a new Python package using the PyDev plugin for the Eclipse IDE, it automatically creates an module. We can also create it ourselves manually, when not using Eclipse.


The module is usually empty and, then, has a size of 0 kilobytes.

We can use this usually empty module to connect different Python modules by entering code into it. This recipe will show how to do this.

Getting ready

We will create a new GUI similar to the one we created in the previous recipe, Avoiding spaghetti code.

How to do it…

As our project becomes larger and larger, we naturally break it out into several Python modules. Sometimes it can be a little bit complicated to find modules that are located in different subfolders, either above or below the code that needs to import it.

One practical way to get around this limitation is to use the module.


In Eclipse, we can set the Eclipse internal project PyDevPYTHONPATH to certain folders and...
