First time webscraper, could you give any pointers?

After surveying a few options, I’d like to stick to what I can do with just the REPL, ideally. Having to install further dependencies or libraries is something I want to avoid, initially at least, so I can learn how to do the basics first. I may be going about this the wrong way. My inspiration for local code and REPL first, libraries and 3rd party code second, comes from here: https://betterprogramming.pub/how-to-scrape-modern-websites-without-headless-browsers-d871bbd1119e

Unfortunately, I am still unable to local the script that is pulling in examples…
