I have a few hundred folders, each with a set of shapefiles that are identical across folders (ie each folder has a 'lot.shp'). They are all supposed to be polygon features, but unfortunately many are line features.

I am trying to convert all line features to polygons using Feature to Polygon.

To do this I have tried the following code which should work through each folder converting the desired shapefiles and saving back into the same folder but with a '2' in the name:

import arcpy, glob, os



filelist = ['buildingpoly','lot', etc etc]



path = "C:/folder_containing_desired_subfolders/*/"



for x in filelist:

    list = glob.glob(path + x + ".shp")

    arcpy.FeatureToPolygon_management(in_features=list, out_feature_class=path + x + "2.shp", cluster_tolerance="", attributes="ATTRIBUTES", label_features="")

    del list

But this gets the following error:

Runtime error Traceback (most recent call last): File "", line 10, in File "c:program files (x86)arcgisdesktop10.4arcpyarcpymanagement.py", line 2524, in FeatureToPolygon raise e ExecuteError: ERROR 000210: Cannot create output C:/folder_containing_desired_subfolders/*/buildingpoly2.shp Failed to execute (FeatureToPolygon).

Any ideas? I'm at a loss on this one.

An alternative that would also work is if I can have all the new polygon features saved in the same directory but this would require each getting a unique name.

Have a try with this code:

import os, sys, arcpy



path = "C:/folder_containing_desired_subfolders"

filelist = ['buildingpoly','lot', etc etc]



for (Spath,Sfiles,Sdirs) in arcpy.da.Walk():

    for ThisFile in Sfiles:

        # break up the file name and extension

        fName, fExt = os.path.splitext(ThisFile)

        if fExt.upper() == '.SHP':

            # only for .shp files

            if fName.lower() in filelist:

                # this fName is in the filelist of interest

                # get some info about the shapefile

                D = arcpy.Describe(os.path.join(Spath,ThisFile))

                if D.shapeType == 'Polyline':

                    # do your polygonization here

                elif D.shapeType == 'Polygon':

                    # do something for the already polygon feature classes

You say all your shapefiles are in subfolders so using arcpy.da.Walk() to traverse the folder tree, finding all Esri recognized feature classes and rasters then break up the file name and extension to filter by extension and then Describe to see if the feature class is a line or polygon.. this should get you a bit closer to where you're headed.
