将信息从 GUI 写入 Excel 工作表

Question

我正在使用 TKinter 开发 GUI 应用程序，用户输入的信息需要使用 Openpyxl 写入 excel 文档。现在，我正在尝试获取从 eng_lst 选项菜单中选择的名称，并将该名称写入 GatewayUpgrade2.xlsx 工作簿的联系人 sheet 的单元格 A3。如何才能做到这一点？谢谢。

这是我得到的错误：

    def UpdateSheet(self, value):
            wb=openpyxl.load_workbook('GatewayUpgrade2.xlsx')
            wb.get_sheet_by_name('Contacts')

UpdateSheet 需要一个名为 value 的输入值。但是对于您没有指定的提交按钮，这个输入值应该是什么。所以改变行

self.submit_bttn = Button(self, text = "Submit", command = self.UpdateSheet).grid(row=10, column=1, sticky=W)

至

value = ... specify the value here
self.submit_bttn = Button(self, text = "Submit", command = lambda: self.UpdateSheet(value)).grid(row=10, column=1, sticky=W)
