Overview of this book

Python is the preferred choice of developers, engineers, data scientists, and hobbyists everywhere. It is a great language that can power your applications and provide great speed, safety, and scalability. It can be used for simple scripting or sophisticated web applications. By exposing Python as a series of simple recipes, this book gives you insight into specific language features in a particular context. Having a tangible context helps make the language or a given standard library feature easier to understand. This book comes with 133 recipes on the latest version of Python 3.8. The recipes will benefit everyone, from beginners just starting out with Python to experts. You'll not only learn Python programming concepts but also how to build complex applications. The recipes will touch upon all necessary Python concepts related to data structures, object oriented programming, functional programming, and statistical programming. You will get acquainted with the nuances of Python syntax and how to effectively take advantage of it. By the end of this Python book, you will be equipped with knowledge of testing, web services, configuration, and application integration tips and tricks.

Making REST requests with urllib

A web application has two essential parts:

  • A client: This can be a user's browser, but may also be a mobile device app. In some cases, a web server may be a client of other web servers.
  • A server: This provides the web services and resources we've been looking at, in the Using the Flask framework for RESTful APIs, and Parsing the query string in a request recipes, as well as other recipes, such as Parsing a JSON request and Implementing authentication for web services.

A browser-based client will generally be written in JavaScript. Mobile apps are written in a variety of languages, with a focus on Java or Kotlin for Android devices and Objective-C with Swift for iOS devices.

There are several user stories that involve RESTful API clients written in Python. How can we create a Python program that is a client of RESTful web services?

We'll assume that we have a web server based on the...
