title: Can't split commas out of list
body: <p>I've got a similar list: 
  list = [',99', ',48', ',48', ',44', ',80', ',82', ',88', ',90', '1,1'] </p>
  
  <p>I just want the number to the right of the comma, but when I try splitting: </p>
  
  <p>newList = list.split(',')</p>
  
  <p>I get:</p>
  
  <p>AttributeError: 'list' object has no attribute 'split'</p>
