In Python DevOps, how do I consume message queues?

In Python DevOps, consuming message queues is a vital process for handling asynchronous communication between different services. Commonly used message queues include RabbitMQ, Apache Kafka, and AWS SQS. Below is an example using the `pika` library to consume messages from a RabbitMQ queue.

import pika # Connect to RabbitMQ server connection = pika.BlockingConnection(pika.ConnectionParameters('localhost')) channel = connection.channel() # Declare a queue (it must be declared in the same way as the producer) channel.queue_declare(queue='hello') # Callback function to process messages def callback(ch, method, properties, body): print(f"Received {body}") # Start consuming messages channel.basic_consume(queue='hello', on_message_callback=callback, auto_ack=True) print('Waiting for messages. To exit press CTRL+C') channel.start_consuming()
