I am creating a python code to iterate through a folder of shapefiles of contour s data load it and then publish it. as part if the script i am trying to get all the files to have the same line color so when it is published it looks consistent. my code loads the data but it not applying the same color to all the layers. How would i accomplish this ?

my code is:

import arcpy import os # Define the folder containing the files q=1 folder_path = r"E:\Macon_Bibb_County_Contour2024\Contour 5 ft" output = f"E:\Macon_Bibb_County_Contour2024\outputs\ 5ft package{q}" tag ="contour, contour 5 ft, elevation, mwa" summ = "5 ft vector tile package from macon bidd lidar data flown 2024" lower=380000 upper=410000 # Define the map and project project = arcpy.mp.ArcGISProject("CURRENT") # Use "CURRENT" for the active ArcGIS Pro project map = project.listMaps()[0] # Get the first map in the project (adjust if needed) for dirpath, dirnames, filenames in os.walk(folder_path): try: for f in filenames: i = f[:-4] if i.isdigit() and lower <= int(i) < upper: if f.endswith(".shp"): full_path =(str(dirpath) +"\\"+f) #print(full_path) l = map.addDataFromPath(full_path) l.symbology.renderer.symbol.Color = "#824924" #set line color #l.append(full_path) except arcpy.ExecuteError: # Handle geoprocessing errors msgs = arcpy.GetMessages(2) arcpy.AddError(msgs) # Return error messages for script tools print(msgs) # Print error messages continue

Arc Pro: 3.5.2

I usually like using Path.rglob for recusrive walking. You also have several errors in your code.

output is an fstring with escaped characters (needs to be fr not just f)
You're accessing a Color attribute of symbol that doesnt exist. It's lowercase color
That color attribute requires a dictionary in the format {'COLORSPACE', [v1,v2,v3,...]}
You're using ExecuteError which I'm not sure you can access after arcpy is initialized?

Here's a version that tries to address those issues:

import arcpy from pathlib import Path from typing import TYPE_CHECKING from collections.abc import Iterator from arcpy.mp import Map, Layer if TYPE_CHECKING: from arcpy._symbology import Symbology, Symbol from arcpy._renderer import SimpleRenderer from arcpy import ExecuteError #type:ignore def shapefiles_in(path: Path) -> Iterator[Path]: """Walk an rglob of shapefiles""" yield from (fl for fl in path.rglob('*.shp') if fl.is_file()) def file_range(files: Iterator[Path], lower: int, upper: int) -> Iterator[Path]: """Filter shapefiles to filename range """ yield from ( fl for fl in files if fl.stem.isdigit() and ( lower <= int(fl.stem) < upper ) ) def add_data(map: Map, shapefile: Path) -> None: """Add the shapefile to the map""" # This is an unwrapped version of the symbol edit that exposes the base # types for each level. It should help you find the issue # (Color is lowercase and needs a dictionary) lay: Layer = map.addDataFromPath(str(shapefile.resolve())) #type:ignore sym: Symbology = lay.symbology rend: SimpleRenderer = sym.renderer #type:ignore symbol: Symbol = rend.symbol #type:ignore symbol.color = {'RGB': [130, 73, 36]} #"#824924" def main() -> None: # Define the folder containing the files q=1 folder_path = Path(r"E:\Macon_Bibb_County_Contour2024\Contour 5 ft") output = Path(fr"E:\Macon_Bibb_County_Contour2024\outputs\ 5ft package{q}") tag ="contour, contour 5 ft, elevation, mwa" summ = "5 ft vector tile package from macon bidd lidar data flown 2024" lower=380000 upper=410000 # Define the map and project project = arcpy.mp.ArcGISProject("CURRENT") # Use "CURRENT" for the active ArcGIS Pro project map = project.listMaps()[0] # Get the first map in the project (adjust if needed) shps = shapefiles_in(folder_path) for fl in file_range(shps, lower, upper): try: add_data(map, fl) except Exception as e: # Handle geoprocessing errors msgs = arcpy.GetMessages(2) arcpy.AddError(msgs) # Return error messages for script tools print(msgs, '\n', e) # Print error messages if __name__ == '__main__': main()
