title: Dynamic Keyword Arguments in Python?
body: <p>Does python have the ability to create dynamic keywords?</p>
  
  <p>For example:</p>
  
  <pre><code>qset.filter(min_price__usd__range=(min_price, max_price))
  </code></pre>
  
  <p>I want to be able to change the <strong>usd</strong> part based on a selected currency.</p>
