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. Its flexible syntax enables developers to write short scripts while at the same time, they can use object-oriented concepts to develop very large projects. 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 uses the simplest programming style, using the fewest lines of code to create a GUI in Python, and then advances to using object-oriented programming in later chapters. If you are new to object-oriented programming (OOP), this book will teach you how to take advantage of the OOP coding style in the context of creating GUIs written in Python. Throughout the book, you will develop an entire GUI application, building recipe upon recipe, connecting the GUI to a database. In the later chapters, you will explore additional Python GUI frameworks, using best practices. You will also learn how to use threading to ensure your GUI doesn’t go unresponsive. By the end of the book, you will be an expert in Python GUI programming to develop a common set of GUI applications.

Using module-level global variables


Encapsulation is a major strength in any programming language that enables us to program using OOP. Python is both OOP and procedural. We can create global variables that are localized to the module they reside in. They are global only to this module, which is one form of encapsulation. Why do we want this? Because, as we add more and more functionality to our GUI, we want to avoid naming conflicts, which could result in bugs in our code.

Note

We do not want naming clashes creating bugs in our code! Namespaces are one way to avoid these bugs, and in Python, we can do this by using Python modules (which are unofficial namespaces).

Getting ready

We can declare module-level globals in any module just above and outside of functions.

We then have to use the global Python keyword to refer to them. If we forget to use global in functions, we will accidentally create new local variables. This would be a bug and something we really do not want to do.
