xlwings 查找特定的字符文本开始和结束位置并格式化

Answer 1

我已更改代码以在工作表的已用数据中包含对文本的 Excel 搜索，然后根据原始代码的需要使用 Bold-Red 更新该单元格文本。
我最终不得不为 Excel 搜索使用 while 循环，并在搜索循环回到第一个找到的单元格时中断。因此，代码会跟踪first_search_cell与 while 循环中找到的下一个单元格进行比较。
我将 Excel 搜索变量保留为常量，因此如果您想更改搜索选项，您就知道名称和值是什么。显然你可以删除你不想要的或者使用 import from Xlwings 常量。
否则它几乎是一样的。
