title: Updating a list of python dictionaries with a key, value pair from another list
body: <p>Let's say I have the following list of python dictionary:</p>
  
  <pre><code>dict1 = [{'domain':'Ratios'},{'domain':'Geometry'}]
  </code></pre>
  
  <p>and a list like:</p>
  
  <pre><code>list1 = [3, 6]
  </code></pre>
  
  <p>I'd like to update <code>dict1</code> or create another list as follows:</p>
  
  <pre><code>dict1 = [{'domain':'Ratios', 'count':3}, {'domain':'Geometry', 'count':6}]
  </code></pre>
  
  <p>How would I do this? </p>
