Learning Python Networking - Second Edition

Overview of this book

Network programming has always been a demanding task. With full-featured and well-documented libraries all the way up the stack, Python makes network programming the enjoyable experience it should be. Starting with a walk through of today's major networking protocols, through this book, you'll learn how to employ Python for network programming, how to request and retrieve web resources, and how to extract data in major formats over the web. You will utilize Python for emailing using different protocols, and you'll interact with remote systems and IP and DNS networking. You will cover the connection of networking devices and configuration using Python 3.7, along with cloud-based network management tasks using Python. As the book progresses, socket programming will be covered, followed by how to design servers, and the pros and cons of multithreaded and event-driven architectures. You'll develop practical clientside applications, including web API clients, email clients, SSH, and FTP. These applications will also be implemented through existing web application frameworks.

Introduction to XML

In this section, we will learn how to work with XML documents, parse them, and extract data from them by using the ElementTree API in Python 3.7. We're going to start by introducing how XML is used in Python, and then we will explain an XML-based API called the Amazon S3 API.

Getting started with XML

XML corresponds to a general standard to serialize data of diverse types in a structured way. The XML standard was published in 1996 by W3C and is used intensively to define data structures.

An XML document is known as an element and contains data structures based on content delimited by markers (markups). These markers correspond to labels (tags) that indicate the beginning and end of the structure they...
