In Python web scraping, how do I consume message queues?

In Python web scraping, consuming message queues can be achieved using libraries such as Redis or RabbitMQ. These message brokers allow you to manage the scraping tasks efficiently by queuing the URLs to be scraped and handling the results appropriately.

Here’s an example of how you might consume messages from a queue using Celery with RabbitMQ:

from celery import Celery app = Celery('scraper', broker='pyamqp://guest@localhost//') @app.task def scrape_url(url): # Code to perform web scraping on the given URL pass # To consume messages from the queue urls_to_scrape = ['http://example.com', 'http://anotherexample.com'] for url in urls_to_scrape: scrape_url.delay(url)
