Applying borders to a cell in OpenPyxl

With openpyxl version 2.2.5, this snippet works for me:

from openpyxl.styles.borders import Border, Side
from openpyxl import Workbook

thin_border = Border(left=Side(style="thin"), 
                     right=Side(style="thin"), 
                     top=Side(style="thin"), 
                     bottom=Side(style="thin"))

wb = Workbook()
ws = wb.get_active_sheet()
# property cell.border should be used instead of cell.style.border
ws.cell(row=3, column=2).border = thin_border
wb.save('border_test.xlsx')

The documentation mentions other values for the style attribute :

Value must be one of {‘double’, ‘dashed’, ‘thin’, ‘medium’,
‘mediumDashDot’, ‘dashDot’, ‘thick’, ‘mediumDashed’, ‘hair’, ‘dotted’,
‘slantDashDot’, ‘mediumDashDotDot’, ‘dashDotDot’}
