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： /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：
