To develop with Twisted, you'll need to learn how to use several new classes and objects. These classes are at the core of Twisted, and you'll use them over and over in your applications. They also represent the steepest part of the Twisted learning curve. Understand how to use them, and the rest of Twisted will be easy; otherwise, you'll struggle (or write lots of unnecessary code).
This chapter shows how to write simple clients and servers with Twisted. Along the way, it introduces Twisted's basic classes, explains how they work, and demonstrates how to use them.
