If you're a developer getting into networking for the first time or an IT pro looking to build practical automation skills, this second edition gives you a clear and structured path to master essential networking concepts and become a confident, hands-on Python network administrator. If you're looking to automate repetitive networking tasks, build tools for infrastructure, or become a network administrator, you'll find this book teaching all the skills, structure, and mindset to make it happen.

You'll start off by getting the basics of Python down and then quickly move on to TCP, UDP, and socket programming. You'll work with protocols like HTTP, FTP, DNS, and email, and you'll use Python to automate everyday network tasks. As you read on, you'll dive into modern network automation using Netmiko, Paramiko, and NAPALM, manage asynchronous tasks with AsyncIO, and set up monitoring and analysis workflows through SNMP, ping3, iperf3, and Locust. You'll also use SimPy to simulate networks, program firewalls, scanning, encryption, and VPNs. You'll also get to work on configuration management and orchestration using Ansible. This will teach you how to automate server and network setups, manage software lifecycles, enforce standards, and integrate Python for advanced logic.

This book is all about clarity and practicality, using simple, easy-to-follow examples that work in the real world. It's not meant to deal with complicated business scenarios, but it does cover the most important, routine and common jobs of network programming.
