title: How to copy over an Excel sheet to another workbook in Python
body: <p>I have a string with a sourcefile path and another string with a destfile path, both pointing to Excel workbooks.</p>
  
  <p>I want to take the first sheet of the sourcefile and copy it as a new tab to the destfile (doesn't matter where in the destfile), then save it.</p>
  
  <p>Couldn't find an easy way in <code>xlrd</code> or <code>xlwt</code> or <code>xlutils</code> to do this. Am I missing something?</p>
