title: python print the data for each column
body: <p>I want to print the data in my excel file, segmenting it by cities names. For example I want to get all the columns for paris and put it in a new sheet, the columns for london and put it in another sheet etc. So far, i could only open the file and print the cities names. What is the method I should follow? So far I have:</p>
  
  <pre><code># -*- coding: utf-8 -*-
  
  
  import openpyxl as px
  workbook = px.load_workbook('digital_trust.xlsx')
  worksheet_names = workbook.get_sheet_names()
  
  for worksheet_name in worksheet_names:
      worksheet = workbook.get_sheet_by_name(worksheet_name)
  
      for row in worksheet.iter_rows():
          ville = row[3].value        
          print ville
  </code></pre>
