Is it possible to do a geoprocess automatically with all the layers of a folder?

[Jose_AlbertoNúñez]

Hi

I have 200 shapefile in a folder. all fo them are similar. I need select by atribute and them aply eliminate tool and save the shapes files. 

Is it possible to do automatically with all the layers from model builder or arcpy? How can I do?

thnak you very much

so before the select by attributes you have to squeeze in a line

arcpy.MakeFeatureLayer_management(fc,"fc_lyr")
‍

then change 'fc' to 'fc_layer' in the selectbyattributes line (going blindly again)

Hi @Dan Patterson

I think understand you:

import arcpy

from arcpy import env
env.overwriteOutput = True
import os

arcpy.env.workspace = r"E:\PLANFOR\PD_G000053VA_N\Carto\A_Monre\Tipos_masa\Prueba_subrodal\Rodales_tipmas.gdb"
fcs = arcpy.ListFeatureClasses()
out_folder = r"E:\PLANFOR\PD_G000053VA_N\Carto\A_Monre\Tipos_masa\Prueba_subrodal\Salida"
for fc in fcs:

arcpy.MakeFeatureLayer_management(fc,"fc_lyr")

arcpy.SelectLayerByAttribute_management(fc_lyr, "NEW_SELECTION", "\"Superfic_1\" <= 3")

out_name = "{}\\{}_elim.shp".format(out_folder, fc_lyr)

arcpy.Eliminate_management(fc_lyr, out_name, "LENGTH", "", "")

But I have a error. I do not find it. Do you see it? Thank you very much

In python code blocks like this loop are marked by indentation of the code, see Dan's original code snippet.

[NeilAyres]

So those 4 lines following "for fc in fcs:"

should be indented, usually 4 spaces

@Neil Ayres @Dan Patterson

I use spaces, I did not that are so important in python, sorry. I think that know is correct but i have a new error,

[DanPatterson_Retired]

"fc_lyr"  in quotes do the same for it on the last line

Hi @Dan Patterson.

I think that the script does not generate errors. I think it performs the same process with all the layers (190). The problem is that since the output file has a unique name "fc_lyr", all the files are rewritten and at the end there is a single file instead of 190. How could I do it to keep the original name files + a sequence so that it does not overwrite?

Thank you very much

in the out_name  line...the... fc_layer ...there should be... fc   

we got carried away replacing fc with fc_layer

[Jose_AlbertoNúñez]

Excellent !! I think it works perfectly
Thank you very much to all the people who have helped me, especially @Dan Patterson.
This is a problem that I had in my workflow and that saved me a lot of work. So far I was doing the process manually.
Thank you!!

Glad it worked out Jose
