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.

Designing the Python GUI database


Before we start creating tables and inserting data into them, we have to design the database. Unlike changing local Python variable names, changing a database schema once it has been created and loaded with data is not that easy.

We would have to DROP the table, which means we would lose all the data that was in the table. So, before dropping a table, we would have to extract the data, then DROP the table, recreate it, and finally reimport the original data.

You get the picture...

Designing our GUI MySQL database means first thinking about what we want our Python application to do with it and then choosing names for our tables that match the intended purpose.

Getting ready

We are working with the MySQL database we created in the previous recipe, Configuring the MySQL database connection. A running instance of MySQL is necessary and the two previous recipes show how to install MySQL, all necessary additional drivers, as well as how to create the database we are...
