slixmpp is a friendly fork of SleekXMPP which goal is to use asyncio instead of threads to handle networking. See Differences from SleekXMPP.

Slixmpp is an MIT licensed XMPP library for Python 3.4+,

Slixmpp’s design goals and philosphy are:

Low number of dependencies

Installing and using Slixmpp should be as simple as possible, without having to deal with long dependency chains.

As part of reducing the number of dependencies, some third party modules are included with Slixmpp in the thirdparty directory. Imports from this module first try to import an existing installed version before loading the packaged version, when possible.

Every XEP as a plugin
Following Python’s “batteries included” approach, the goal is to provide support for all currently active XEPs (final and draft). Since adding XEP support is done through easy to create plugins, the hope is to also provide a solid base for implementing and creating experimental XEPs.
Rewarding to work with
As much as possible, Slixmpp should allow things to “just work” using sensible defaults and appropriate abstractions. XML can be ugly to work with, but it doesn’t have to be that way.

Here’s your first Slixmpp Bot:

import asyncio
import logging

from slixmpp import ClientXMPP

class EchoBot(ClientXMPP):

    def __init__(self, jid, password):
        ClientXMPP.__init__(self, jid, password)

        self.add_event_handler("session_start", self.session_start)
        self.add_event_handler("message", self.message)

        # If you wanted more functionality, here's how to register plugins:
        # self.register_plugin('xep_0030') # Service Discovery
        # self.register_plugin('xep_0199') # XMPP Ping

        # Here's how to access plugins once you've registered them:
        # self['xep_0030'].add_feature('echo_demo')

    def session_start(self, event):

        # Most get_*/set_* methods from plugins use Iq stanzas, which
        # are sent asynchronously. You can almost always provide a
        # callback that will be executed when the reply is received.

    def message(self, msg):
        if msg['type'] in ('chat', 'normal'):
            msg.reply("Thanks for sending\n%(body)s" % msg).send()

if __name__ == '__main__':
    # Ideally use optparse or argparse to get JID,
    # password, and log level.

                        format='%(levelname)-8s %(message)s')

    xmpp = EchoBot('', 'use_getpass')
