title: How to use StringIO in Python3?
body: <p>I am using Python 3.2.1 and I can't import the <code>StringIO</code> module. I use 
  <code>io.StringIO</code> and it works, but I can't use it with <code>numpy</code>'s <code>genfromtxt</code> like this:</p>
  
  <pre><code>x="1 3\n 4.5 8"        
  numpy.genfromtxt(io.StringIO(x))
  </code></pre>
  
  <p>I get the following error:</p>
  
  <pre><code>TypeError: Can't convert 'bytes' object to str implicitly  
  </code></pre>
  
  <p>and when I write <code>import StringIO</code> it says</p>
  
  <pre><code>ImportError: No module named 'StringIO'
  </code></pre>
