  <p>Note: Just started programming in Python using Sublime Text 3. I am not sure why I am getting the white dots/mark on every line, see image below. I would like learn the following.</p>
  
  <ol>
  <li>Is it because of an error?</li>
  <li>Is it because of a package or command?</li>
  <li>I tried CTRL+Space,CTRL+G and CTRL+K and I still get the white marks, shall I be concerned? </li>
  </ol>
