title: How to format a part of a string in python?
body: <p>What I want to do is:  </p>
  
  <pre><code>property = "name"
  formatter = "my %s is %s" % property
  print formatter % "wong2" // "my name is wong2"
  </code></pre>
  
  <p>but the first line gives "not enough arguments for format string" error.  </p>
