title: Carriage return '\r' stops working when pwntools are imported in python3
body: <p>I have this little method to print overlapping strings of 80 characters:</p>
  
  <pre><code>def print80(s):
      pad = ' '*(80-len(s))
      print((s+pad)[:80], end='\r')
  </code></pre>
  
  <p>It works well, but if I import <a href="http://docs.pwntools.com/en/stable/" rel="nofollow noreferrer"><code>pwntools</code></a>, for example with <code>import pwn</code>, it stops working: the <code>\r</code> character is no longer printed.</p>
