Build a Web Scraper (Python)
Build a real web scraper in Python with requests and BeautifulSoup - fetch, parse, extract structured data, paginate politely, and save it - run on your own machine.
- Setup and Fetch a Page Set up a clean Python environment, install requests and BeautifulSoup, then fetch a real page and confirm it came back OK.
- Parsing the HTML Load the fetched HTML into BeautifulSoup and locate elements two ways - with the find/find_all methods and with CSS selectors.
- Extracting Structured Data Turn loose page elements into clean dictionaries - one record per item - with tidy text and code that survives a missing field.
- Pagination and Being Polite Follow next-page links through a whole catalog while staying a good guest - delays, a real User-Agent, robots.txt, rate limits, and the ethics and law of scraping.
- Saving the Data, and Where to Take It Write your collected records to CSV and JSON to finish the working scraper, then map the upgrades - a database, scheduling, and headless browsers for JavaScript-heavy sites.
