arcgis中用python脚本批量给多个要素类的相同字段赋值

1、python脚本

import arcpy# 设置工作空间路径
arcpy.env.workspace = r"D:\test.gdb"# 要素集名称
feature_dataset = "test"# 线要素类名称列表，初始化为空
line_feature_classes = []# 遍历要素集获取所有线要素类
for fc in arcpy.ListFeatureClasses(feature_dataset=feature_dataset):desc = arcpy.Describe(feature_dataset + "/" + fc)if desc.shapeType == "Polyline":line_feature_classes.append(fc)# 字段名称列表
field_names = ["QCX_COORD", "QDY_COORD", "ZDX_COORD", "ZDY_COORD"]# 开启编辑会话
edit = arcpy.da.Editor(arcpy.env.workspace)
edit.startEditing()# 开启对每个线要素类的编辑操作并赋值
for fc in line_feature_classes:try:edit.startOperation()with arcpy.da.UpdateCur
