插个广告，制作ArcGIS的Tool工具学习下面的教程就对了：

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 importarcpy4 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 inpart:12 ifpoint: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：
