Have you used a repl before? Try getting beautiful soup objects in a REPL (like bpython) and seeing what methods they have, or try reading the docs at http://www.crummy.com/software/BeautifulSoup/bs4/doc/

I find https://www.debuggex.com/ really useful for debugging Python regular expressions - be sure to change the language on the dropdown from JavaScript to Python.

I mention a REPL because that makes answering questions like "are beautiful soup objects compatible with regex" pretty easy. (turns out they're not, you'll need to use regex with the text you get out of a beautiful soup object)

I misunderstood you, looks like you totally can - see http://www.crummy.com/software/BeautifulSoup/bs4/doc/#a-regular-expression

My comments would mostly be to break this up into more functions, in order to give names to the things you're doing at each step. I'd make url a parameter instead of hardcoding it. In lines 30/31, a "set" is would better
