Eventlet

Python based networking library that lets you right (near) synchronous code and use asynchronous I/O under the covers

Eventlet is a concurrent networking library for Python that allows you to change how you run your code, not how you write it. * It uses epoll or libevent for highly scalable non-blocking I/O. * Coroutines ensure that the developer uses a ... [More] blocking style of programming that is similar to threading, but provide the benefits of non-blocking I/O. * The event dispatch is implicit, which means you can easily use Eventlet from the Python interpreter, or as a small part of a larger application.

"Now compare this to Twisted or Tornado. Twisted tries so damn hard to be Java that it really offends me personally. Those developers strike me as the alpha-programmer types who see no reason not to rewrite an existing codebase for a 20% performance ... [More] gain. Tornado on the other hand is significantly less Jersey Shore douchebaggy, but they still miss the point: we are programmers who need to get stuff done. Inventing your own HTTP client class, when Python's builtin works just fine if not better is the type of hubris that gets hotshot programmers fired in their first month." -- Ted Dziuba [Less]
