| This code sets up a callback function that will be called every time a message is received from the 'my_queue' queue. The `auto_ack` parameter specifies whether to automatically acknowledge the message after it has been processed. Finally, the `start_consuming` method starts consuming messages from the queue. | This code sets up a callback function that will be called every time a message is received from the 'my_queue' queue.

| An exchange in RabbitMQ is a messaging entity that receives messages from producers and routes them to queues based on some criteria. When a producer sends a message to RabbitMQ, it sends the message to an exchange. The exchange then examines the message's routing key and decides which queue(s) the message should be sent to. | An exchange in RabbitMQ is a messaging entity that receives messages from producers and routes them to queues based on some criteria.

| Each exchange type has its own routing algorithm and is used in different messaging scenarios. Understanding the exchange types is important when designing RabbitMQ architectures that meet specific business requirements. | Each exchange type has its own routing algorithm and is used in different messaging scenarios.
