*** - Web scraping is a technique used to extract large amounts of data from websites, whereby the data is extracted and saved to a local file in your computer or to a database in a tabular form. - Here is how a typical web scraping process works: - A web scraper sends a GET request to the URL that you have instructed it to scrape. - The server responds to the request by returning the HTML content of the webpage. - The web scraper then parses the HTML content of the page, filters out the data it needs, and saves this data into a format you want (usually as a spreadsheet or CSV file). - Web scraping is used widely in several contexts, including data mining, data analysis, and data integration. > [!WARNING] > Please be aware that web scraping should be done with respect for the website's terms of service. Some websites explicitly forbid web scraping in their terms of service or "robots.txt" file, and scraping such sites can potentially lead to legal troubles. > > Also, it's important to be considerate and not overload a website's server with scraping requests, as this could disrupt the service for other users.
