title: If statement with multiple conditions using regex
body: <p>I would like to loop through pull requests in GitHub and if the pull request has the comments in the code below, do something (for now, print the pull request number).  I have a pull request that has the comments I'm looking for (spread over multiple comments in the pull request), but it doesn't print the pull request number.  I suspect it has something to do with the regex I'm using because if I break the if statement down to look for just the regex or the string values, it works fine, but when I try to combine them in one if statement, it doesn't work.  </p>
  
  <p>I don't think this is a duplicate question as I've looked at all the suggestions under questions that may already have your answer.</p>
  
  <pre><code>    for pr in repo.pull_requests():
          #check to ensure pull request meets criteria before processing
          conflicts_base_branch = "This branch has no conflicts with the base branch"
          checks = "All checks have passed"
          sign_off_comment_present = re.compile(r"\B#sign-off\b", re.IGNORECASE)
          for comment in list(repo.issue(pr.number).comments()):
              if (conflicts_base_branch and checks in comment.body) and (sign_off_comment_present.search(comment.body)):
                  print(pr.number)
