title: Comparing list of Counters in Python
body: <p>I have a list of counters in python:</p>
  
  <pre><code>[Counter({12.011: 30.0, 15.999: 2.0}),
  Counter({12.011: 12.0, 15.999: 2.0}),... Counter({12.011: 40.0, 
  15.999: 5.0, 79.904: 5.0})]
  </code></pre>
  
  <p>How do I find the count of each Counter element. Counter gives me an error of unhashable type. Another way I thought is to iterate through the list in a nested for-loop, checking if each counter is equal to any other counter in the list and increment a dictionary accordingly. Is there a better solution?</p>
