Web scraping is the process of extracting specific data from the internet automatically. It has many use cases, like getting data for a machine learning project, creating a price comparison tool, or any other innovative idea that requires an immense amount of data.
While you can theoretically do data extraction manually, the vast contents of the internet makes this approach unrealistic in many cases. So knowing how to build a web scraper can come in handy.
But first, I should warn you about the legality of web scraping. While the act of scraping is legal, the data you may extract can be illegal to use. Make sure that you're not messing with any:
Generally speaking, you should always read a website's terms and conditions before scraping to make sure that you're not going against their policies. If you're ever unsure how to proceed, contact the site owner and ask for consent.
