Python 如何通过tkinter下拉列表中的输入从excel导入特定单元格值？

我现在有这个代码，我想在其中添加另一个因素，当我从下拉列表中选择一个特定年份，从另一个中选择村庄时，我想要横截面值。e、 g村庄从下拉列表中选择=阿巴德加尔，选择年份=2021，头部标签中的值应为=8.41。类似地，如果我选择2022，它应该是8.02，依此类推。

将其分解为几个步骤：首先需要找到包含abad garh的行，然后需要在所选年份的列中获取单元格。如果只查找几次，搜索Excel文件就可以了。如果需要多次搜索，则应将文件解析为数据结构，以便更快地查找。@代码学徒我有1000行35列的数据，但只想在excel中工作，因为我的代码几乎准备好了……。只剩下这一步。我的第一条注释解释了如何实现这一点。
