title: Get Excel-Style Column Names from Column Number
body: <p>This is the code for providing the COLUMN name when the row and col ID is provided but when I give values like <code>row = 1 and col = 104</code>, it should return <code>CZ</code>, but it returns <code>D@</code></p>
  
  <pre><code>row = 1
  col = 104
  div = col
  column_label = str()
  while div:
      (div, mod) = divmod(div, 26)
      column_label = chr(mod + 64) + column_label
  
  print column_label
  </code></pre>
  
  <p>What is wrong with what I am doing?</p>
  
  <p>(This code is in reference for EXCEL Columns, where I provide the Row,Column ID value and expect the ALPHABETIC value for the same.)</p>
