title: Python file interface for strings
body: <p>Is there a Python class that wraps the <code>file</code> interface (read, write etc.) around a string? I mean something like the <code>stringstream</code> classes in C++.</p>
  
  <p>I was thinking of using it to redirect the output of <code>print</code> into a string, like this</p>
  
  <pre><code>sys.stdout = string_wrapper()
  print "foo", "bar", "baz"
  s = sys.stdout.to_string() #now s == "foo bar baz"
  </code></pre>
