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.

Connecting to the Cloud

It seems that nearly every application needs to talk to the outside world sooner or later, and your ABQ Data Entry application is no exception. You've received some new feature requests that will require some interactions with remote servers and services.

First, the quality assurance division is doing a study of how local weather conditions are impacting the environmental data in each lab; they've requested a way to download and store local weather data in the database on demand. The second request is from your manager, who is still required to upload daily CSV files to the central corporate servers. She would like this process streamlined and available at a mouse click.

In this chapter, you will learn to interface with the cloud in the following topics:

  • In HTTP using urllib, you'll connect to web services and download data using urllib.
  • In RESTful HTTP using requests, you'll learn to interact with REST services...
