title: Delete blank entries in CSV file Python
body: <p>I need to read in a CSV file, from Excel, whose rows may be an arbitrary length. </p>
  
  <p>The problem is the python retains these blank entries, but need to delete them for a future algorithm. Below is the output, I don't want the blank entries.</p>
  
  <pre><code>     ['5', '1', '5', '10', '4', '']
       ['3', '1', '5', '10', '2', '']
       ['6', '1', '5', '10', '5', '2']
       ['9', '10', '5', '10', '7', '']
       ['8', '5', '5', '10', '7', '']
       ['1', '1', '5', '10', '', '']
       ['2', '1', '5', '10', '1', '']
       ['7', '1', '5', '10', '6', '4']
       ['4', '1', '5', '10', '3', '1']
