For at least one exercise, we’re going to need to scrape data from a web site. (Depending on the direction you choose for your final project, you may need to do this again. In any case, it can be a handy thing to know how to do.) We’ll use Google’s Chrome web browser and the Scraper extension to get this done.<\/p>\n
