Twisted is an event-driven networking engine written in Python. This talk is for people familiar with programming in Python who would like to be introduced to Twisted. We will discuss event-driven programming in general and will look at a few commonly-used classes which support it, showing their use in code examples. We will demonstrate a couple of simple servers and clients. We will talk about the Twisted Application Framework and show its use in a network service. We will examine clients for existing, supported protocols, such as web and IRC. We will talk about where to find information about Twisted, and how to join the community.
