title: Converting list to dict python
body: <p>Given a list:</p>
  
  <pre><code>source = [{'A':123},{'B':234},{'C':345}]
  </code></pre>
  
  <p>I need a dict from this list in the format:</p>
  
  <pre><code>newDict  = {'A':123,'B':234,'C':345}
  </code></pre>
  
  <p>What is the syntactically cleanest way to accomplish this?</p>
