Twisted

Twisted is an extensible framework in Python with a focus on event-driven network programming. Twisted has multiprotocol integration that includes HTTP, FTP, SMTP, POP3, IMAP4, DNS, IRC, MSN, OSCAR, XMPP/Jabber, telnet, SSH, SSL, NNTP, Finger, ident, and many more. Hence, it helps to quickly implement most of the custom server/services network applications.

All the features in Twisted have a cooperating API. Also, none of the functionality is implemented by blocking the network, so we don't need to use threading. Twisted can handle thousands of connections in a single thread.

Some of the modules included in Twisted are as follows:

• twisted.web: Used for HTTP clients and servers, HTML templating, and a WSGI server.

• twisted.conch: Used for SSHv2 and Telnet clients and servers and to create terminal emulators.

• twisted.words: Used to create IRC, XMPP, and other IM protocols, clients, and servers.

• twisted.mail: Used for IMAPv4, POP3, SMTP clients, and servers.

• twisted.positioning: Helps...
