我需要将列添加到基于 csv 的“匹配”形状文件中。我还有最后一步要完成，即从 csv 获取要输入 shp 的值。
我明白了
readCSV[rowID] Traceback（最近一次调用最后一次）：文件“”，第 1 行，类型错误：'_csv.reader' 对象不可下标
精简后的 CSV 是
文件看起来像
该代码将 OVL_CAT + OVL2_DESC 与文件名匹配。
然后，我获取代码以添加名为 LGA_CODE 的列，并需要使用第 2 行第 1 列的“583094”填充它...当我无法调用 FileList 2以从 csv 获取第 2 行时，我该如何获取（在下面的示例中为 3，但在 python 中为 2）？
