RabbitMQ is an open source message queuing software and is used to provide reliable communication between messages. It facilitates asynchronous messaging between components in large and complex systems using the AMQP (Advanced Message Queuing Protocol) protocol. This enables high efficiency and an unbreakable connection between applications.
Basic Components of RabbitMQ
- Producer: It is the component that produces messages.
- Consumer: It is the component that receives and processes messages from the queue.

You can use the pika library to work with RabbitMQ in Python. You should install this library first:
pip install pika
