title: beautiful soup vs selenium vs urllib
body: <p>I am working on a web automation project. I need to be able to pull pages, assess data, and be able to interact with the page (e.g. login, enter values, and post to the site.) As a derivative of the logins, I think I will need something that will allow me to remain logged in given a credential (e.g. store the credential or cookies.)</p>
  
  <p>I've already used UrlLib &amp; Requests libraries to pull files and the pages themselves.</p>
  
  <p>I am trying to decide on the best Python library for the task.</p>
  
  <p>Any suggestions would be highly appreciated.</p>
  
  <p>thank you!</p>
