Openpyxl 更新文件数据而不是创建新文件

Question

我正在构建一个小工具来检查网站上的超链接是否会消失或保留。该程序到目前为止有效，但总是创建一个新文件并删除一天前创建的最新文件 sheet（我每天使用脚本）。

我的代码如下

    def save_results(excel_urls,erg):
        currentdate = str(date.today())
        excel_file = openpyxl.load_workbook('Links2.xlsx')
        excel_sheet = excel_file['Sheet']
        book = Workbook()
        sheet = book.active
        #this following code is from my main sheet to keep it in the following file as well. its also not a proper update function but works so far. 
        sheet.column_dimensions['A'].width = 60
        sheet.column_dimensions['B'].width = 60
        for row in excel_sheet.values:
            sheet.append(row)
        #Here im going to create the other sheets with the results of my crawl
        book.create_sheet(currentdate)
        book[currentdate].column_dimensions['A'].width = 60
        book[currentdate].column_dimensions['B'].width = 60
        for keys,values in enumerate(excel_urls):
            y = values[0], str(erg[keys])
            book[currentdate].append(y)
        book.save('Links2.xlsx')

我找不到只更新而不覆盖现有文件的方法。在结果安全之前包含读取的所有内容的功能也可以正常工作。

提前感谢您的帮助！

我的函数实际上不起作用。

    excel_file = openpyxl.load_workbook('Links2.xlsx')
    book = Workbook()
    for z,i in enumerate(excel_file.sheetnames):
        book.create_sheet('{}'.format(i))
        print(excel_file.sheetnames[z])
        for row in excel_file[excel_file.sheetnames[i]].values:
            #print(row)
            excel_file[excel_file.sheetnames[i]].append(row)
    book.save('Links2.xlsx')```

def save_exisiting_data():      
    excel_file = openpyxl.load_workbook('Links2.xlsx')
    book = Workbook(write_only=True)
    for z, i in enumerate(excel_file.sheetnames):
        book.create_sheet('{}'.format(i))
        book[i].column_dimensions['A'].width = 60
        book[i].column_dimensions['B'].width = 60
        for row in excel_file[excel_file.sheetnames[z]].values:
            book[excel_file.sheetnames[z]].append(row)
