title: How to create QString in PyQt4?
body: <pre><code>&gt;&gt;&gt; from PyQt4 import QtCore
  &gt;&gt;&gt; str = QtCore.QString('Hello')
  AttributeError: 'module' object has no attribute 'QString'
  
  &gt;&gt;&gt; QtCore.QString._init_(self)
  AttributeError: 'module' object has no attribute 'QString' 
  </code></pre>
  
  <p>Yes, I've read <a href="http://pyqt.sourceforge.net/Docs/PyQt4/qstring.html" rel="noreferrer">QString Class Reference</a>   </p>
  
  <p>Why can't I import <code>QString</code> from <code>QtCore</code>, as specified in the docs ? </p>
