title: Print in one line dynamically
body: <p>I would like to make several statements that give standard output without seeing newlines in between statements.</p>
  
  <p>Specifically, suppose I have:</p>
  
  <pre><code>for item in range(1,100):
      print item
  </code></pre>
  
  <p>The result is:</p>
  
  <pre><code>1
  2
  3
  4
  .
  .
  .
  </code></pre>
  
  <p>How get this to instead look like:</p>
  
  <pre><code>1 2 3 4 5 ...
  </code></pre>
  
  <p>Even better, is it possible to print the single number <em>over</em> the last number, so only one number is on the screen at a time?</p>
