I've been trying to use this code to add a field to, merge, and sort multiple feature classes:

import arcpy, os

arcpy.env.workspace = r'W:\S&P\s&p techs\Emily\TownshipsDissolved\FinalDissolved.gdb'

#Looping through dissolved feature classes, adding 'Name' field and writing
#feature class name in the added field.
fcs = arcpy.ListFeatureClasses()

for fc in fcs:
    arcpy.AddField_management(fc, "Name", "TEXT", field_length = 50)
    with arcpy.da.UpdateCursor(fc, "Name") as cursor:
      for row in cursor:
        row[0] = fc

#Merging the multiple feature classes into one named OSRS_ORN_NER.
mergeOutput = r'W:\S&P\s&p techs\Emily\TownshipsDissolved\FinalDissolved.gdb\OSRS_ORN_NER'
sortOutput = r'W:\S&P\s&p techs\Emily\TownshipsDissolved\FinalDissolved.gdb\OSRS_ORN_NER_new'

arcpy.Merge_management(fcs, mergeOutput)

#Sorting by HWY_NUM_PR and replacing OSRS_ORN_NER by the sorted feature class.

arcpy.Sort_management(mergeOutput, sortOutput, [["HWY_NUM_PR", "ASCENDING"]])

but when I run it I get an error that says this: enter image description here

does anyone know what I'm doing wrong??

    Could it be to do with your path names? Its bad practice to use & and spaces in folder names. – Hornbydd Jan 19 '15 at 19:51
  • just for checking, what does print fcs return ? Aren't your features in a feature dataset ? – radouxju Jan 19 '15 at 21:56
  • @radouxju I think it is correct to ask this as a new question rather than "as an edit of your previous question" because the earlier question already has an (accepted) answer that might become invalidated. – PolyGeo Jan 19 '15 at 22:23
  • Please try to always include the text (not screenshots) of code and errors because that way they can be searched. – PolyGeo Jan 19 '15 at 22:24

I think you should use Windows Explorer to copy W:\S&P\s&p techs\Emily\TownshipsDissolved\FinalDissolved.gdb to C:\temp and then try replacing:

r'W:\S&P\s&p techs\Emily\TownshipsDissolved\FinalDissolved.gdb'



as a test to see whether it is a problem with your pathname containing an ampersand and/or a space.
