title: Print on same line at the first in python 2 and 3
body: <p>There are several solutions for printing on same line and at the first of it, like below.</p>
  
  <p>In python 2,</p>
  
  <pre><code>print "\r Running... xxx",
  </code></pre>
  
  <p>And in Python 3,</p>
  
  <pre><code>print("\r Running... xxx", end="")
  </code></pre>
  
  <p>I can't find a single print solution to cover python 2 and 3 at the same time. Do I have to use <code>sys.stdout.write</code>?</p>
