The automated process of extracting data from web pages is known as web scraping. The process involves downloading the HTML content of a web page, parsing it, and then retrieving the required data from it. Python's robust toolkit, which includes programs like Beautiful Soup and Scrapy, makes web scraping tasks straightforward and effective. Incremental data extraction, in addition to web scraping, is a useful tactic for dealing with large amounts of data or websites that frequently change their content. Retrieving only newly added or changed data since the previous extraction is the aim of incremental data extraction. Python offers several techniques for incremental data extraction processes, such as timestamp-based methods, pagination, and caching.
