有示例要素类如下
经过下面代码处理
1 #遍历输出面或折线要素的折点坐标 2 #infc：输入要素类
# code source： https://www.cnblogs.com/yzhyingcool/
# QQ：975601416 3 import arcpy 4 infc='test'; 5 for row in arcpy.da.SearchCursor(infc,["OID@","SHAPE@"]): 6 print("Feature{}:".format(row[0]+1)) 7 part_num=1 8 for part in row[1]: 9 print("Part{}:".format(part_num)) 10 pnt_num=1 11 for point in part: 12 if point: 13 print("Point{}:{},{}".format(pnt_num,point.X,point.Y)) 14 else: 15 print("Interior Ring:") 16 pnt_num-=1 17 pnt_num+=1 18 part_num+=1
输出结果如下：
