title: Passing a string using argparse
body: <p>I've been reading through the documentation and the tutorial, but there is one thing I don't quite understand. </p>
  
  <pre><code>import argparse
  parser = argparse.ArgumentParser()
  parser.add_argument("test string", type=str, help="this is a string")
  args = parser.parse_args()
  print args
  </code></pre>
  
  <p>When I run <code>$python prog.py 'test'</code> the result is:</p>
  
  <p><code>Namespace(test string='test')</code></p>
  
  <p>How do I get it to print just <code>test</code>? </p>
