Python：如何从文本文件创建点形状文件

我正在编写一个 python代码来读取多边形形状文件中的点并将它们保存在点形状文件中.
所以首先我制作了一个文本文件并将点'(x,y)存储在该.txt文件中.然后我尝试从文本文件中创建一个点形状文件,但它给出了一个错误.
这是代码(只是最后一部分)：

creat point shape-file from text file 
import fileinput
import string
import os
env.overwriteOutput=True
outpath="C:/roadpl"
newfc="newpoint.shp" 
arcpy.CreateFeatureclass_management(outpath,newfc,"Point")
infile="C:/roadpl/roadL5.txt"
cursor=arcpy.da.InsertCursor(newfc,["SHAPE@"])
array=arcpy.Array()
for line in fileinput.input(infile):
    X,Y=string.split(line," ")
    array.add(arcpy.Point(X,Y))
cursor.insertRow([arcpy.Point(array)])
fileinput.close()
del cursor

这是错误：

Traceback (most recent call last):
  File "C:Lab5P_Code_L5",line 49,in <module>
    point.X,point.Y  = line.split()
  File "C:Program Files (x86)ArcGISDesktop10.1arcpyarcpyarcobjects_base.py",line 87,in _set
    return setattr(self._arc_object,attr_name,cval(val))
