In Python data visualization, how do I consume message queues?

In Python, consuming message queues can be accomplished using libraries like `pika` for RabbitMQ, `kafka-python` for Apache Kafka, or `redis-py` for Redis. These libraries allow you to subscribe to message queues, receive messages, and process them as needed. Below is an example of consuming messages from a RabbitMQ queue using the `pika` library.

import pika # Establish a connection to RabbitMQ connection = pika.BlockingConnection(pika.ConnectionParameters('localhost')) channel = connection.channel() # Declare the queue (this creates the queue if it doesn't already exist) channel.queue_declare(queue='my_queue') # Callback function to process messages def callback(ch, method, properties, body): print("Received:", body) # Set up the consumer channel.basic_consume(queue='my_queue', on_message_callback=callback, auto_ack=True) print('Waiting for messages. To exit press CTRL+C') channel.start_consuming()
