body: <p>I want to be able to turn csv file into a list of lists with the column values for each list. For example:</p>
  
  <pre><code>6,2,4
  5,2,3
  7,3,6
  </code></pre>
  
  <p>into</p>
  
  <pre><code>[[6,5,7],[2,2,3],[4,3,6]]
  </code></pre>
  
  <p>Ive only managed to open the file and only having success printing it as rows</p>
  
  <pre><code>with open(input,'rb') as csvfile:
          csv_file = csv.reader(csvfile)
  
          header = csv_file.next() 
  
          raw_data = csv_file
