python openpyxl实现添加读写操作（主要针对xlsx格式）

from openpyxl import Workbookfrom openpyxl.compat import rangefrom openpyxl.utils import get_column_letter

dest_filename = 'empty_book1.xlsx'wb = Workbook()ws1 = wb.activews1.title = "range names"for row in range(1, 40):   ws1.append(range(600))ws3 = wb.create_sheet(title="Data")for row in range(10, 20):   for col in range(27, 54):       _ = ws3.cell(column=col, row=row, value="%s" % get_column_letter(col))print(ws3['AA10'].value)wb.save(filename = dest_filename)sheet_ranges = wb['range names']print(sheet_ranges['D18'].value)ws3.cell(column=27,row=11,value='aaa')wb.save(filename = dest_filename)
