File Path Variables not working in Newer Versions of Python

EvanMyers1

I have a script that uses the Project geoprocessing tool and my script is giving me the "Parameters are not valid" error.   

The weird thing is my script works fine in python 2.7 but not in the python environment created by ArcGIS Pro 3.0.3 (python 3.9.11).  I have tried os.path.exists and it comes back as True in both versions.  I have tried the tool in ArcGIS Pro using the same file paths, tool works, I then export the tool as python script, doesn't work.

 

 

workspaceforCodes = "W:\\GIS\\Tools\\WorkspacesForTools\\Sync.gdb"
PBCGIS_BaseConnection = "W:\\GIS\\WORKING FILES\\EM Working Files\\Databases\\Source.sde"
fcSource = PBCGIS_BaseConnection + "\\PARCELS"
projectedOutput = workspaceforCodes + "\\PARCELS_reprojected"
print("Cleaning up workspace.  Removing old Reprojected Parcels.")
if arcpy.Exists(projectedOutput):
    arcpy.Delete_management(projectedOutput)
try:
    print("Reprojecting PARCELS to be Florida State Plane.")   # arcpy.Project_management
    arcpy.management.Project(in_dataset=fcSource, out_dataset=projectedOutput,
                             out_coor_system="102658",
                             transform_method="NAD_1983_To_HARN_Florida",
                             in_coor_system="102258",
                             preserve_shape="NO_PRESERVE_SHAPE", max_deviation="", vertical="NO_VERTICAL")
    print("PAO.PARCELS dataset reprojected to 'NAD_1983_StatePlane_Florida_East_FIPS_0901_Feet'"
          " from 'NAD_1983_HARN_StatePlane_Florida_East_FIPS_0901'")

except():
    print("Projecting PBC Parcels failed. Check the variables for the 'Project' geoprocessing tool")

Code appears sound, besides the spaces in the file paths making my eye twitch. 😉

 

I'm not sure why those paths are tripping up the tool. In additon to os.path.exists, you could try os.access(fcSource, os.R_OK):

 

import os

# Check if the file is readable
if os.access(fcSource, os.R_OK):
    print(f"You have read permission on the file {fcSource}")
else:
    print(f"You do not have read permission on the file {fcSource}")

 

Also, you shouldn't need to... but you could try using "pathlib".

 

from pathlib import Path
import arcpy

workspaceforCodes = Path("W:/GIS/Tools/WorkspacesForTools/Sync.gdb")
PBCGIS_BaseConnection = Path("W:/GIS/WORKING FILES/EM Working Files/Databases/Source.sde")
fcSource = PBCGIS_BaseConnection / "PARCELS"
projectedOutput = workspaceforCodes / "PARCELS_reprojected"

print("Cleaning up workspace. Removing old Reprojected Parcels.")
if arcpy.Exists(str(projectedOutput)):
    arcpy.Delete_management(str(projectedOutput))
try:
    print("Reprojecting PARCELS to be Florida State Plane.")
    arcpy.management.Project(in_dataset=str(fcSource), out_dataset=str(projectedOutput), out_coor_system="102658", transform_method="NAD_1983_To_HARN_Florida", in_coor_system="102258", preserve_shape="NO_PRESERVE_SHAPE", max_deviation="", vertical="NO_VERTICAL")
    print("PAO.PARCELS dataset reprojected to 'NAD_1983_StatePlane_Florida_East_FIPS_0901_Feet' from 'NAD_1983_HARN_StatePlane_Florida_East_FIPS_0901'")
except Exception as e:
    print(f"Projecting PBC Parcels failed. Check the variables for the 'Project' geoprocessing tool: {e}")
