Overview of this book

Tkinter is widely used to build GUIs in Python due to its simplicity. In this book, you’ll discover Tkinter’s strengths and overcome its challenges as you learn to develop fully featured GUI applications. Python GUI Programming with Tkinter, Second Edition, will not only provide you with a working knowledge of the Tkinter GUI library, but also a valuable set of skills that will enable you to plan, implement, and maintain larger applications. You’ll build a full-blown data entry application from scratch, learning how to grow and improve your code in response to continually changing user and business needs. You’ll develop a practical understanding of tools and techniques used to manage this evolving codebase and go beyond the default Tkinter widget capabilities. You’ll implement version control and unit testing, separation of concerns through the MVC design pattern, and object-oriented programming to organize your code more cleanly. You’ll also gain experience with technologies often used in workplace applications, such as SQL databases, network services, and data visualization libraries. Finally, you’ll package your application for wider distribution and tackle the challenge of maintaining cross-platform compatibility.

Summary

In this chapter, you learned how to work with a relational SQL database. You installed and configured PostgreSQL. You converted a flat-file dataset into relational tables by identifying the primary key fields, choosing correct data types, and normalizing the data structure to reduce the possibility of inconsistencies, redundancies, and anomalies. You learned how to install and work with the psycopg2 library for retrieving and storing data in PostgreSQL. Finally, you went through the arduous task of building a SQL database to hold your ABQ data, building a database model class to interface with the database, and converting the application code to use the new SQL backend.

In the next chapter, we'll be reaching out to the cloud. We'll need to contact some remote servers using different networking protocols to exchange data. You'll learn about the Python standard library's module for working with HTTP, as well as third-party packages for connecting with...
