title: How to convert list of key-value tuples into dictionary?
body: <p>I have a list that looks like:</p>
  <pre><code>[('A', 1), ('B', 2), ('C', 3)]
  </code></pre>
  <p>I want to turn it into a dictionary that looks like:</p>
  <pre><code>{'A': 1, 'B': 2, 'C': 3}
  </code></pre>
  <p>What's the best way to go about this?</p>
  <p>EDIT: My list of tuples is actually more like:</p>
  <pre><code>[(A, 12937012397), (BERA, 2034927830), (CE, 2349057340)]
  </code></pre>
  <p>I am getting the error <code>ValueError: dictionary update sequence element #0 has length 1916; 2 is required</code></p>
