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.

RESTful HTTP using requests

You've been asked by your manager to create a function in your program that will allow her to upload a CSV extract of the daily data to ABQ's corporate web services, which uses an authenticated REST API. REST stands for REpresentational State Transfer and refers to an approach to web services that is built around advanced HTTP semantics to provide a more code-friendly interface. Services designed around the REST concept are described as RESTful. Let's take a deeper look at how REST interactions work.

Understanding RESTful web services

A RESTful service is built around the idea of accessing resources. A resource is typically a data record or file, though it could also be something like a remote procedure or hardware interface. We access resources via endpoints, which are URLs that represent a particular resource.

We have seen that web servers typically allow you to fetch data using GET and submit data using POST. REST APIs, however...
