python中怎么利用openpyxl 新增sheet

from openpyxl import load_workbookworkbook = load_workbook(filename = "xxxxdata.xlsx")sheet_list = workbook.sheetnames

import pandas as pd xls = pd.ExcelFile('xxxxxdata.xlsx')df1 = pd.read_excel(xls, '6.1',header=1)sheet_list_left =[  '6.2', '6.3', '6.4', '6.5', '6.7', '6.8', '6.9', '6.10', '6.11', '6.12', '6.14', '6.15', '6.16', '6.18', '6.17', '6.19', '6.21']

for each_sheet in sheet_list_left:    print(each_sheet)    df_each = pd.read_excel(xls,each_sheet,header=1 )    df_each= df_each[['采购姓名', '上架产品数量', '销售总金额', '连云港', '徐淮临日盐', '扬州']]    df_each['日期'] =  each_sheet    df1 = df1.append(df_each)

import openpyxlimport pandas as pdwriter = pd.ExcelWriter('xxxxdata.xlsx',engine='openpyxl')book = openpyxl.load_workbook(writer.path)writer.book = bookdf1.to_excel(writer, "新sheet名",index=False)writer.save()
