title: How to find the min/max value of a common key in a list of dicts?
body: <p>I have a list of dictionaries like so:</p>
  <pre class="lang-py prettyprint-override"><code>[{'price': 99, 'barcode': '2342355'}, {'price': 88, 'barcode': '2345566'}]
  </code></pre>
  <p>I want to find the <code>min()</code> and <code>max()</code> prices. Now, I can sort this easily enough using a key with a lambda expression (as found in another Stack Overflow post), so if there is no other way I'm not stuck. However, from what I've seen there is almost always a direct way in Python, so this is an opportunity for me to learn a bit more.</p>
