I am trying to add multiple fields to an attribute table using the same attribute's tables current field names. I want the new fields to be text fields that can be populated with either yes or no later on. When I run the script below I get the error above. The script works halfway through and crashes. Any help or suggestions are welcome.
import arcpy
from arcpy import env
# To allow overwriting the outputs change the overwrite option to true.
arcpy.env.overwriteOutput = True
# ###############################################################################
# [1] Script adds duplicate (text) fields to attribute table with shortened name
# Allows for Yes and No values to be added to table
# Identify shapefile
blocks = r"C:\Users\Workspace\scrap\FB_CFDReport.shp"
# Generate list for each field in blocks
fields = arcpy.ListFields(blocks)
# For loop creates duplicate text fields in block shapefile
for field in fields:
field4 = field.name
f4 = field4[0:8] + "X"
print(f4)
arcpy.AddField_management(blocks, f4, "TEXT")
#arcpy.SelectLayerByAttribute_management(blocks, selection_type="NEW_SELECTION", where_clause= field+ " > 0", invert_where_clause="")
#arcpy.CalculateField_management(blocks, f4, 'Yes')
#arcpy.SelectLayerByAttribute_management(blocks, selection_type="NEW_SELECTION", where_clause= field+" = 0", invert_where_clause="")
#arcpy.CalculateField_management(blocks, f4, 'No')
