However why asynchronous code? What’s it? How does it profit us?

After all you’re not going to be scraping all the trillions of pages directly however the concept is that scraping occasion 1,000 pages would take a really very long time doing it synchronously (like utilizing Python requests and/or simply selenium).
Should you’ve achieved loads of net scraping earlier than however by no means used Python’s aysncio, this course will assist you to higher perceive the basics and deliver your scraping recreation to a different stage.
