Perpetuating Inbox Zero means living in a constant state of vigilance, aggressively and swiftly responding to every incoming message. It means becoming an email answering machine!

Twisted Python: The engine of your Internet

Learn to build event-driven client and server applications

I want to build a web server, a mail server, a BitTorrent client, a DNS server, or an IRC bot—clients and servers for a custom protocol in Python. And I want them to be cross-platform, RFC-compliant, testable, and deployable in a standardized fashion. What library should I use?

Use Twisted

Twisted is a “batteries included” networking engine for writing, testing, and deploying event-driven clients and servers in Python. It comes with off-the-shelf support for popular networking protocols like HTTP, IMAP, IRC, SMTP, POP3, IMAP, DNS, FTP, and more.

To see just how easy it is to write networking services using Twisted, let’s run and discuss a simple Twisted TCP echo server:

With Twisted installed, if we save this code to echoserver.py and run it with python echoserver.py, clients can now connect to the service on port 8000, send it data, and get back their echoed results. Read more…
