title: Appending over a loop onto different lists
body: <p>Say I have a list of these values:</p>
  
  <pre><code>['1', '91', '70', '2', '84', '69', '3', '86', '68', '4', '84', '68', '5', '83', '70', '6', '80', '68', '7', '86', '73', '8', '89', '71', '9', '84', '67', '10', '83', '65', '11', '80', '66', '12', '86', '63', '13', '90', '69', '14', '91', '72', '15', '91', '72', '16', '88', '72', '17', '97', '76', '18', '89', '70', '19', '74', '66', '20', '71', '64', '21', '74', '61', '22', '84', '61', '23', '86', '66', '24', '91', '68', '25', '83', '65', '26', '84', '66', '27', '79', '64', '28', '72', '63', '29', '73', '64', '30', '81', '63', '31', '73', '63']
  </code></pre>
  
  <p>How would I take each first element over three and append it to another list? So for example, 1, and then 2, and then 3... making <code>[1,2,3....31]</code></p>
  
  <p>And then respectively the second being <code>[91, 84, 86,......73]</code></p>
  
  <p>and the same for the third <code>[70, 69, 68......63]</code></p>
  
  <p>Any help would be great?</p>
  
  <p>I am using a loop now and trying to append the value to different lists.</p>
