How Python Data Engineers Use Beautiful Soup

Python data engineers use Beautiful Soup to scrape structured data from HTML pages as part of web ingestion pipelines. It is typically paired with the requests library for fetching pages and used to extract tables, product listings, article content, and government data from websites that do not offer APIs. Scraped data is then cleaned with Pandas and loaded into a database or data warehouse as part of an ETL workflow.
