Get started with Twisted, the event-driven networking framework written in Python.

With this introductory guide, you’ll learn the key concepts and design patterns to build event-driven client and server applications for many popular networking protocols. You’ll also learn the tools to build new protocols using Twisted’s primitives.

Start by building basic TCP clients and servers, and then focus on deploying production-grade applications with the Twisted Application infrastructure. Along the way, you can play with and extend examples of common tasks you’ll face when building network applications. If you’re familiar with Python, you’re ready for Twisted.

Learn the core components of Twisted servers and clients
Write asynchronous code with the Deferred API
Construct HTTP servers with Twisted’s high-level web APIs
Use the Agent API to develop flexible web clients
Configure and deploy Twisted services in a robust and standardized fashion
Access databases using Twisted’s nonblocking interface
Add common server components: logging, authentication, threads and processes, and testing
Explore ways to build clients and servers for IRC, popular mail protocols, and SSH

Jessica McKellar is a software engineer from Cambridge, MA. She enjoys the Internet, networking, low-level systems engineering, and contributing to and helping other people contribute to open source software. She is a Twisted maintainer, organizer for the Boston Python user group, and a local STEM volunteer.

Abe Fettig is a software developer and maintainer of Hep, an open source message server that makes it possible to transparently route information between RSS, email, weblogs, and web services. He speaks frequently at software conferences including PyCon and lives in Portland, Maine with his wife, Hannah.
