Python GUI Programming - A Complete Reference Guide

By: Alan D. Moore, B. M. Harwani

Overview of this book

A responsive graphical user interface (GUI) helps you interact with your application, improves user experience, and enhances the efficiency of your applications. With Python, you’ll have access to elaborate GUI frameworks that you can use to build interactive GUIs that stand apart from the rest. This Learning Path begins by introducing you to Tkinter and PyQt, before guiding you through the application development process. As you expand your GUI by adding more widgets, you'll work with networks, databases, and graphical libraries that enhance its functionality. You'll also learn how to connect to external databases and network resources, test your code, and maximize performance using asynchronous programming. In later chapters, you'll understand how to use the cross-platform features of Tkinter and Qt5 to maintain compatibility across platforms. You’ll be able to mimic the platform-native look and feel, and build executables for deployment across popular computing platforms. By the end of this Learning Path, you'll have the skills and confidence to design and build high-end GUI applications that can solve real-world problems. This Learning Path includes content from the following Packt products: Python GUI Programming with Tkinter by Alan D. Moore Qt5 Python GUI Programming Cookbook by B. M. Harwani

HTTP using requests

You've been asked to create a function in your program to upload a CSV extract of the daily data to ABQ's corporate web services, which uses an authenticated REST API. While urllib is easy enough to use for simple one-off GET and POST requests, complex interactions involving authentication tokens, file uploads, or REST services can be frustrating and complicated using urllib alone. To get this done, we'll turn to the requests library.

REST stands for REpresentational State Transfer, and is the name used for web services built around advanced HTTP semantics. In addition to GET and POST, REST APIs use additional HTTP methods like DELETE, PUT, and PATCH, along with data formats like XML or JSON, to present an API with a complete range of interactions.

The third-party requests library is highly recommended by the Python community for any serious work...
