title: Change openpyxl Excel Worksheet to Landscape Orientation
body: <p>I have tried and failed for longer than I care to admit.  I have read the documentation.  Stumped.  Any guidance greatly appreciated!!! Thanks...Ellie The Good Dog</p>
  
  <p>This block is OK:</p>
  
  <pre><code>import openpyxl
  myexcel = openpyxl.Workbook()
  mysheet = myexcel.active
  mysheet['A1'] = 'Test'
  mysheet.print_area = 'A1:Z1'
  myexcel.save(r'C:\Temp\Testing.xlsx')
  </code></pre>
  
  <p>This block fails:</p>
  
  <pre><code>from openpyxl.worksheet import page
  mysheet.page.orientation = 'landscape'
  mysheet.orientation = 'landscape'
  mysheet.worksheet.ORIENTATION_LANDSCAPE = 'landscape'
  mysheet.worksheet.page.ORIENTATION_LANDSCAPE = 'landscape'
  mysheet.worksheet.ORIENTATION = 'landscape'
  mysheet.worksheet.page.ORIENTATION = 'landscape'
  </code></pre>
