title: Chrome extension: sending a variable (url) to python
body: <p>I'm trying to make a Chrome extension that gets the url of the pages a user visits, and from there would send it to Python where I could do things like natural language processing, etc. I would then want to send something back to be displayed in the extension popup, although I'm not completely sure what yet.</p>
  
  <p>I can't figure out how to send the url to Python.</p>
  
  <p>I'm <em>very</em> new at all of this so any help/insight would be appreciated! I haven't been able to find anything online that I understood about doing this.</p>
