title: Python count multiple values in dictionary of list
body: <p>I have been trying to count the values in a dictionary with respect to the key. However, I could not achieved desired result. I will demonstrate with more details below:</p>
  
  <pre><code>from collections import Counter
  d = {'a': ['Adam','Adam','John'], 'b': ['John','John','Joel'], 'c': ['Adam','Adam','John}
  # create a list of only the values you want to count,
  # and pass to Counter()
  c = Counter([values[1] for values in d.itervalues()])
  print c
  </code></pre>
  
  <p>My output:</p>
  
  <pre><code>Counter({'Adam': 2, 'John': 1})
  </code></pre>
  
  <p>I want it to count everything in the list, not just first value of the list. Also, I want my result to be with respect to the key. I will show you my desired output below:</p>
  
  <pre><code>{'a': [{'Adam': 1, 'John': 2}, 'b':{'John': 2, 'Joel': 1}, 'c':{'Adam': 2, 'John': 1 }]}
  </code></pre>
  
  <p>Is it possible to get this desired output? Or anything close to it? I would like to welcome any suggestions or ideas that you have. Thank you.</p>
