Learning Python Networking - Second Edition

By: José Manuel Ortega, Dr. M. O. Faruque Sarker, Sam Washington

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.

Engaging with Email

Email is one of the most popular forms of digital communication. Python has a rich number of built-in libraries for dealing with emails. In this chapter, you will learn how to use Python to compose, send, and retrieve emails with the Simple Mail Transfer Protocol (SMTP), Post Office Protocol 3 (POP3), and Internet Message Access Protocol (IMAP) protocols. Practical code examples in Python 3.7 will illustrate most of these concepts in detail.

The following topics will be covered in this chapter:

  • Learning about and understanding email protocols
  • Sending emails with SMTP through the smtplib library
  • Learning the POP3 protocol and retrieving emails with poplib
  • Retrieving emails on the email server using IMAP with imapclient and imaplib
