Python GUI programming with Tkinter

By: Alan D. Moore

Overview of this book

Tkinter is a lightweight, portable, and easy-to-use graphical toolkit available in the Python Standard Library, widely used to build Python GUIs due to its simplicity and availability. This book teaches you to design and build graphical user interfaces that are functional, appealing, and user-friendly using the powerful combination of Python and Tkinter. After being introduced to Tkinter, you will be guided step-by-step through the application development process. Over the course of the book, your application will evolve from a simple data-entry form to a complex data management and visualization tool while maintaining a clean and robust design. In addition to building the GUI, you'll learn how to connect to external databases and network resources, test your code to avoid errors, and maximize performance using asynchronous programming. You'll make the most of Tkinter's cross-platform availability by learning how to maintain compatibility, mimic platform-native look and feel, and build executables for deployment across popular computing platforms. By the end of this book, you will have the skills and confidence to design and build powerful high-end GUI applications to solve real-world problems.

Chapter 12. 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 boss, 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 the following topics:

  • Connecting to web services and downloading data using urllib
  • Managing more complex HTTP interactions using the requests library
  • Connecting and uploading to FTP services using ftplib
