title: Unix: Have Python script constantly running best practice?
body: <p>I have a Python script which process data off of a HTTP data stream and I need this script to in theory be running at all times and forever unless I kill it off manually to update it and run it again.</p>
  
  <p>I was wondering what the best practice to do this was on a Unix (Ubuntu in particular) so that even if Terminal is closed etc the script continues to run in the background unless the process or server are shut down?</p>
  
  <p>Thanks </p>
