title: Creating a separate Counter() object and Pandas DataFrame for each list within a list of lists
body: <p>All the other answers I could find specifically referred to aggregating across all of the nested lists within a list of lists, where as I'm looking to aggregate separately for each list.</p>
  
  <p>I currently have a list of lists:</p>
  
  <pre><code>master_list = [[a,a,b,b,b,c,c,c], [d,d,d,a,a,a,c,c,c], [c,c,c,a,a,f,f,f]]
  </code></pre>
  
  <p>I want to return a dictionary or Counter() objects for each list with a loop:</p>
  
  <pre><code>counter1 = {'a': 2, 'b': 3, 'c': 3}
  counter2 = {'d': 3, 'a': 3, 'c': 3}
  counter3 = {'c': 3, 'a': 2, 'f': 3}
  </code></pre>
  
  <p>Currently, I'm returning something that looks like this using a loop - it's not exactly what I want as it's all lumped together and I'm having trouble accessing the counter objects separately:</p>
  
  <pre><code>Input:
  
  count = Counter()
  for lists in master_list:
      for words in lists:
      count[words] += 1
  
  
  Output:
  
  Counter({'a': 2, 'b': 3, 'c': 3})
  Counter({'d': 3, 'a': 3, 'c': 3})
  Counter({'c': 3, 'a': 2, 'f': 3})
  </code></pre>
  
  <p>The problem with the above is that I can't seem to figure out a way to grab each Counter individually, because I'm trying to create a pandas dataframe for each one of these dictionaries/counter objects. I'm trying to do this programmatically because my "master_list" has hundreds of lists within it and I want to return a dataframe that shows the frequency of the elements for each separate list. In the end I would have a separate dataframe and Counter object for every list within "master-list"</p>
  
  <p>Currently I have something that returns only 1 dataframe:</p>
  
  <pre><code>Input:
  
  table = pandas.DataFrame(count.items())
  table.columns = ['Word', 'Frequency']
  table.sort_values(by=['Frequency'], ascending = [False])
  
  
  Output:
  
  Word   Frequency
  the    542
  and    125
  or     45
  .      .
  .      .
  .      .
  .      .
  </code></pre>
  
  <p>Any insight would be appreciated - also, any tips on handling Counter() objects seperately would be appreciated.</p>
