title: Accessing enumeration constants in Excel COM using Python and win32com
body: <p>I'm using python 2.7 win32com module to load an MS Excel worksheet from Python:</p>
  
  <pre><code>    book = xlApp.Workbooks.Open("myFile.xls")
      sheet = book.Sheets(1)
  </code></pre>
  
  <p>Many methods and properties of Range, Worksheet etc use enumerations like XlDirection, XlFillWith, and so forth. These define constants such as xlDown, xlUp, xlFillWithContents, etc. Are those constants available from win32com so that I could do, for example:</p>
  
  <pre><code>    column = outputsSheet.Range("I5:I150")
      lastRow = column.End(xlInterop.xlDown)
      print "Last row:", lastRow.Row
  </code></pre>
  
  <p>This doesn't work because xlInterop is not defined, is there a way to access it using win32com? Discovering the values of such constants as xlDown by trial and error is not very practical. </p>
