I was working through an exercise designed to teach basic Python skills in ArcMap using Python 2.7. The file below consists of 34 pairs of x,y coordinates. The script creates a new empty polyline feature class, and then use this list of coordinates to create a new polyline. This requires the use of an insert cursor to create new rows and an array object to contain the point objects. Here is the original proposed script:
In the Spyder IDE with the ArcGIS Pro conda installation for 2.3, I hit a number of exceptions that I worked through as follows:
import arcpy
import fileinput
import string
import os
from arcpy import env
env.workspace = "C:/Workspace"
env.overwriteOutput = True
arcpy.CreateFeatureclass_management(r"C:/Results", "newfc", "POLYLINE", None, "DISABLED", "DISABLED", None, None, 0, 0, 0, None)
infile = "C:/coordinates.txt"
cursor = arcpy.da.InsertCursor("newfc.shp", ["SHAPE@"])
array = arcpy.Array()
for line in fileinput.FileInput(infile):
ID, X, Y = (float(infile.split(line," "))
array.add(arcpy.Point(X, Y))
cursor.insertRow([arcpy.Polyline(array)])
fileinput.close()
del cursor
However, there is a syntax error related to the arcpy.Array() method.
File "C:/create.py", line 21
array.add(arcpy.Point(X, Y))
^
SyntaxError: invalid syntax
Here is the point file.
My knowledge is limited and wondered if someone knows if this is a Python version issue and where to find more info, or if they have an answer to the syntax error problem I articulated above.

in case its not what you are thinking.
