title: Python csv list
body: <p>I have a csv file that I process this way. The csv containing just numbers is such:</p>
  <p>1, 5, 6, 8, 45, 56</p>
  <p>2, 6, 34, 42, 56, 98</p>
  <p>1, 5, 6, 8, 45, 56</p>
  <p>...</p>
  <pre><code>import csv
  
  numbers = []
  
  with open('example.csv', newline='') as f:
      reader = csv.reader(f)
      for row in reader:
          numbers.append(row)        
                 
  print(numbers)
  </code></pre>
  <p>output:</p>
  <pre><code>[[1, 5, 6, 8, 45, 56], [2, 6, 34, 42, 56, 98], [1, 5, 6, 8, 45, 56]]
  </code></pre>
  <p>How can I make it print the most frequently occurring lists?
  For example: 1, 5, 6, 8, 45, 56 2 times in list?</p>
