用Arcpy编写点线面要素转ASCII文本（txt）

最近在学Arcpy顺带做了点线面要素转线要素的实验
arcpy一定要先下arcpy，然后在环境里面选择arcpy的py框架
以下为实验数据：

注意：运行程序时一定要关闭arcmap一定要！

（1）我先做的是点、线、面要素的特征点转换为文本文件
以下为脚本截图
以下为点矢量转txt文本

#coding:utf-8
import  arcpy

txtPath = r"C:\Users\lenovo\Desktop\arcpy\test\points.txt"#不能识别汉字
shpPath = r"C:\Users\lenovo\Desktop\arcpy\test\点.shp"

with open(txtPath, "w") as filename:
    cur = arcpy.SearchCursor(shpPath)
    filename.write("Points" + "\n")
    pointindex = 0
    index = 0
    for r in cur:
        index=index+1
        geom = r.shape
        point = geom.getPart()
        #for point in points:
        info = str(pointindex) + " " + str(point.X) + " " + str(point.Y) + "\n"
        filename.write((info))
        pointindex = pointindex + 1
    print index
    print "finished"

此为线矢量转txt文本

#coding:utf-8
import  arcpy

txtPath = r"C:\Users\leno
