Pika is a RabbitMQ (AMQP-0-9-1) client library for Python.
Introduction
Pika is a pure-Python implementation of the AMQP 0-9-1 protocol including RabbitMQ’s
extensions.
Python 2.6+ and 3.3+ are supported.
Since threads aren’t appropriate to every situation, it doesn’t
require threads. It takes care not to forbid them, either. The same
goes for greenlets, callbacks, continuations and generators. It is
not necessarily thread-safe however, and your mileage will vary.
People may be using direct sockets, plain old select(),
or any of the wide variety of ways of getting network events to and from a
python application. Pika tries to stay compatible with all of these, and to
make adapting it to a new environment as simple as possible.

Example
Here is the most simple example of use, sending a message with the BlockingConnection adapter:
import pika
connection = pika.BlockingConnection()
channel = connection.channel()
channel.basic_publish(exchange='example',
routing_key='test',
body='Test Message')
connection.close()
And an example of writing a blocking consumer:
import pika
connection = pika.BlockingConnection()
channel = connection.channel()
for method_frame, properties, body in channel.consume('test'):
# Display the message parts and ack the message
print(method_frame, properties, body)
channel.basic_ack(method_frame.delivery_tag)
# Escape out of the loop after 10 messages
if method_frame.delivery_tag == 10:
break
# Cancel the consumer and return any pending messages
requeued_messages = channel.cancel()
print('Requeued %i messages' % requeued_messages)
connection.close()
Pika provides the following adapters
BlockingConnection - enables blocking, synchronous operation on top of library for simple uses
LibevConnection - adapter for use with the libev event loop http://libev.schmorp.de
SelectConnection - fast asynchronous adapter
TornadoConnection - adapter for use with the Tornado IO Loop http://tornadoweb.org
TwistedConnection - adapter for use with the Twisted asynchronous package http://twistedmatrix.com/
