Python GUI Programming Cookbook - Third Edition

By: Burkhard Meier

Overview of this book

Python is a multi-domain, interpreted programming language that is easy to learn and implement. With its wide support for frameworks to develop GUIs, you can build interactive and beautiful GUI-based applications easily using Python. This third edition of Python GUI Programming Cookbook follows a task-based approach to help you create effective GUIs with the smallest amount of code. Every recipe in this book builds upon the last to create an entire, real-life GUI application. These recipes also help you solve problems that you might encounter while developing GUIs. This book mainly focuses on using Python’s built-in tkinter GUI framework. You'll learn how to create GUIs in Python using simple programming styles and object-oriented programming (OOP). As you add more widgets and expand your GUI, you will learn how to connect to networks, databases, and graphical libraries that greatly enhance the functionality of your GUI. You’ll also learn how to use threading to ensure that your GUI doesn't become unresponsive. Toward the end, you’ll learn about the versatile PyQt GUI framework, which comes along with its own visual editor that allows you to design GUIs using drag and drop features. By the end of the book, you’ll be an expert in designing Python GUIs and be able to develop a variety of GUI applications with ease.

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, save the data in a temporary table or other data format, and then DROP the table, recreate it, and finally reimport the original data.

I hope you are getting the picture of how tedious this could be.

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