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.

Storing and retrieving data from our MySQL database

We will use our Python GUI to insert data into our MySQL database tables. We have already refactored the GUI we built in the previous recipes in our preparation for connecting and using a database.

We will use two textbox entry widgets into which we can type the book or journal title and the page number. We will also use a ScrolledText widget to type our favorite book quotations into, which we will then store in our MySQL database.

Getting ready

This recipe will build on the MySQL database and tables we created in the previous recipes.

How to do it…

We will insert, retrieve, and modify our favorite quotations using our Python GUI. We have refactored the MySQL tab of our GUI in preparation for this:

In order to make the buttons do something, we will connect them to callback functions as we did in the previous recipes. We will display the data in the ScrolledText widget below the buttons.

In order to do this, we will import the MySQL...
