title: iterate through all rows in specific column openpyxl
body: <p>I cannot figure out how to iterate through all rows in a specified column with openpyxl.</p>
  
  <p>I want to print all of the cell values for all rows in column "C"</p>
  
  <p>Right now I have:</p>
  
  <pre><code>from openpyxl import workbook
  path = 'C:/workbook.xlsx'
  wb = load_workbook(filename = path)
  ws=wb.get_sheet_by_name('Sheet3')
  
  for row in ws.iter_rows():
      for cell in row:
          if column == 'C':
              print cell.value
  </code></pre>
