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.

Performing Network Automation with Python and Ansible

Ansible is an open source, general-purpose automation tool written in Python. It can be used to automate servers, network devices, load balancers, and more. In this chapter, you will learn about the principles of Ansible and how we can interact with it from Python. Ansible is used to bring structure and consistency to system deployments, implementations, and changes. In this chapter, we will explore Ansible and learn how to write a Python script to do a networking-automation task with Ansible and how to write an Ansible module with Python.

The following topics will be covered in this chapter:

  • Basics of Ansible
  • Ansible's components and architecture
  • Automating network Python tasks with Ansible
  • Writing Ansible modules with Python
