rmqp = RabbitMQProducer(
    host='localhost', port=5672, virtual_host='/', 
    username='guest', password='guest', 
    exchange='test_exc', exchane_type='topic'

def my_callback_function(ch, method, properties, body):
    # GETTING MESSAGE
    message = body.decode()
    
    # PERFORM YOUR LOGIC HERE
    
    # ACKNOWLEDGE WORK IS DONE
    ch.basic_ack(delivery_tag=method.delivery_tag)
    return None

Following sample code will allow you to receive message from rabbitmq server.

from rabbitmq_utils.consumer import RabbitMQConsumer

# STARTING RABBITMQ CONSUMER
rmqc = RabbitMQConsumer(
        host='localhost', port=5672, virtual_host='/', 
        username='guest', password='guest', exchange='test_exc', 
        queue_name='test_que', routing_key='test_key', exchane_type='topic',
    	my_callback_function
