Code Sample

DeleteFeatures example 1 (Python window)

The following Python window script demonstrates how to use the DeleteFeatures tool in immediate mode.

import arcpy
from arcpy import env
env.workspace = "C:/data"
arcpy.CopyFeatures_management("majorrds.shp", "C:/output/output.gdb/majorrds2")
arcpy.DeleteFeatures_management("C:/output/output.gdb/majorrds2")
DeleteFeatures example 2 (stand-alone script)

The following stand-alone script demonstrates how to use the DeleteFeatures tool to delete features based on an expression.

# Name: DeleteFeatures_Example2.py
# Description: Delete features from a feature class based on an expression
 
# Import system modules
import arcpy
from arcpy import env
 
# Set environment settings
env.workspace = "C:/data/airport.gdb"
 
# Set local variables
inFeatures = "parcels"
outFeatures = "C:/output/output.gdb/new_parcels"
tempLayer = "parcelsLayer"
expression = arcpy.AddFieldDelimiters(tempLayer, "PARCEL_ID") + " = 'Cemetery'"
 
try:
    # Execute CopyFeatures to make a new copy of the feature class
    arcpy.CopyFeatures_management(inFeatures, outFeatures)
 
    # Execute MakeFeatureLayer
    arcpy.MakeFeatureLayer_management(outFeatures, tempLayer)
 
    # Execute SelectLayerByAttribute to determine which features to delete
    arcpy.SelectLayerByAttribute_management(tempLayer, "NEW_SELECTION", 
                                            expression)
 
    # Execute GetCount and if some features have been selected, then 
    #  execute DeleteFeatures to remove the selected features.
    if int(arcpy.GetCount_management(tempLayer).getOutput(0)) > 0:
        arcpy.DeleteFeatures_management(tempLayer)
         
except Exception as e:
    # If an error occurred, print line number and error message
    import traceback
    import sys
    tb = sys.exc_info()[2]
    print("Line {0}".format(tb.tb_lineno))
    print(e.message)

Environments
