title: Dynamic terminal printing with python
body: <p>Certain applications like hellanzb have a way of printing to the terminal with the appearance of dynamically refreshing data, kind of like top().</p>
  
  <p>Whats the best method in python for doing this?  I have read up on logging and curses, but don't know what to use.  I am creating a reimplementation of top.  If you have any other suggestions I am open to them as well.  </p>
