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.

Preface

Configuring different debug output levels


In this recipe, we will configure different debug levels, which we can select and change at runtime. This allows us to control how much we want to drill down into our code when debugging our code.

We will create two new Python classes and place both of them into the same module.

We will use four different logging levels and write our debugging output to a log file we will create. If the logs folder does not exist, we will create it automatically as well.

The name of the log file is the name of the executing script, which is our refactored GUI.py. We can also choose other names for our log files by passing in the full path to the initializer of our Logger class.

Getting ready

We will continue using our refactored GUI.py code from the previous recipe.

How to do it…

First, we create a new Python module into which we place two new classes. The first class is very simple and defines the logging levels. This is basically an enumeration:

class LogLevel:
