title: How to generate a `kwargs` list?
body: <p>From an external file I generate the following dictionary:</p>
  
  <pre><code>mydict = { 'foo' : 123, 'bar' : 456 }
  </code></pre>
  
  <p>Given a function that takes a <code>**kwargs</code> argument, how can generate the keyword-args from that dictionary?</p>
