感谢您的帮助！
我有一个电子表格，其中记录了我的收入和支出，以及日期，描述，借方和贷方金额。我想使用openpyxl来自动化添加特定类别中的值的过程，该程序现在可以正常工作，但是问题是：当我搜索工作表中不存在的短语时，程序崩溃，它无法完成不存在的搜索词组之前和之后的假定操作。
例如， 当我想计算搜索短语“工资”的小计并将小计放入目标单元格时，它工作正常。当我要求程序寻找在那里不存在的东西时，问题就会出现。
我要求程序寻找工资，创建小计，可以正常工作，并假设将值存储在已定义的目标上，当我要求程序寻找税（不存在）时，程序什么都没显示，然后我要求程序获取租金小计（已存在）。该程序无法进行更改。
我在这方面还比较陌生。...因此再次感谢您的帮助！ ：）

也许是一个很好的选择
try:
your code
except:
pass
并在其中运行您的代码，并尝试通过该代码跳过错误。如果发生任何异常，它将忽略此消息并将其运行。
