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.

EDIT:

Here is code that works. It works through the folders and converts all polylines to polygons.

import os, sys, arcpy
directory = "C:/working_folder/"

for path, path_names, data_names in arcpy.da.Walk(directory, type="Polyline"):
 for data_name in data_names:
 arcpy.FeatureToPolygon_management(in_features= (os.path.join(path, data_name)), out_feature_class= (os.path.join(path, "two"+data_name)), cluster_tolerance="", attributes="ATTRIBUTES", label_features="")

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(path):
 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.
