Question

下面显示的程序的目标是根据两个条件输出语句：（Year和Location）完成后，我的下一个目标是将year与{{Yearlink匹配1}}和Location与location。 location和year都是输入语句。输出应该是一个输出该行值的语句。出于某种原因，我总是收到一个错误，有关太多的值要解压缩。如果有人想要更好地了解我所谈论的内容，我的excel表格会被发布。无论如何我尝试了一切，但没有任何东西对我有效。

您是否考虑过使用DictReader？这个变量解包似乎有点像代码味道，并且更容易出错，而不是只是将整行加载到字典中。

错误：使用CSV文件解压缩的值太多
