copy cell style openpyxl

Question

I am trying to copy a sheet, default_sheet, into a new sheet new_sheet in the same workbook.

I did managed to create a new sheet and to copy the values from default sheet. How can I also copy the style of each cell into the new_sheet cells?

new_sheet = workbook.create_sheet()
new_sheet.title = sheetName
default_sheet = workbook.get_sheet_by_name('default')
new_sheet = workbook.get_sheet_by_name(sheetName)
for row in default_sheet.rows:
    col_idx = float(default_sheet.get_highest_column())
starting_col = chr(65 + int(col_idx))
for row in default_sheet.rows:
    for cell in row:
        new_sheet[cell.get_coordinate()] = cell.value
        <copy also style of each cell>

I am at the moment using openpyxl 1.8.2, but i have in mind to switch to 1.8.5.

One solution is with copy:

from copy import copy, deepcopy

new_sheet._styles[cell.get_coordinate()] = copy(
        default_sheet._styles[cell.get_coordinate()])

As of openpyxl 2.5.4, python 3.4: (subtle changes over the older version below)

new_sheet = workbook.create_sheet(sheetName)
default_sheet = workbook['default']

from copy import copy

for row in default_sheet.rows:
    for cell in row:
        new_cell = new_sheet.cell(row=cell.row, column=cell.col_idx,
                value= cell.value)
        if cell.has_style:
            new_cell.font = copy(cell.font)
            new_cell.border = copy(cell.border)
            new_cell.fill = copy(cell.fill)
            new_cell.number_format = copy(cell.number_format)
            new_cell.protection = copy(cell.protection)
            new_cell.alignment = copy(cell.alignment)

For openpyxl 2.1

new_sheet = workbook.create_sheet(sheetName)
default_sheet = workbook['default']

for row in default_sheet.rows:
    for cell in row:
        new_cell = new_sheet.cell(row=cell.row_idx,
                   col=cell.col_idx, value= cell.value)
        if cell.has_style:
            new_cell.font = cell.font
            new_cell.border = cell.border
            new_cell.fill = cell.fill
            new_cell.number_format = cell.number_format
            new_cell.protection = cell.protection
            new_cell.alignment = cell.alignment
