title: does xlwt support xlsx Format
body: <p>I have searched into google and found some contradiction. Does xlwt support xlsx file (MS office 2007). I heard that xlwt 0.7.4 support xlsx file. Does anyone tried xlsx file writing operation with xlwt 0.7.4</p>
  
  <p>The purpose of this question is,I do not have permission to install library if I need to install I need to provide more detail info. I need to write xlsx file in python.So if anyone has done similar thing it will help to provide better inforamtion</p>
  
  <p>I have looked into this wiki page. <a href="https://pypi.python.org/pypi/xlwt" rel="noreferrer">https://pypi.python.org/pypi/xlwt</a>  But did not find that it support xlsx file</p>
  
  <p>or Should I use <a href="https://pypi.python.org/pypi/openpyxl" rel="noreferrer">https://pypi.python.org/pypi/openpyxl</a> for writing xlsx File</p>
