arcpy根据给定坐标值生成要素，要素的坐标有偏移？

import arcpy



# A list of features and coordinate pairs

feature_info = [[[1, 2], [2, 4], [3, 7]],

                [[6, 8], [5, 7], [7, 2], [9, 5]]]



# A list that will hold each of the Polygon objects

features = []



for feature in feature_info:

    # Create a Polygon object based on the array of points

    # Append to the list of Polygon objects

    features.append(

        arcpy.Polygon(

            arcpy.Array([arcpy.Point(*coords) for coords in feature])))



# Persist a copy of the Polyline objects using CopyFeatures

arcpy.CopyFeatures_management(features, "c:/geometry/polygons.shp")
