I have 2 identical feature class with unique ID, I want to get All IDS from both classes which 
NEW exists in feature  Class 1 not exists in feature Class 2

DELETED exists in feature  Class 2 not exists in feature Class 1

 

Any ready code?

To get unique values in a field, I've used.

 

import arcpy

featureClass = r"C:\Default.gdb\Export_Output_10"
fields = ['FEATUREID']

listOfValues=[]

with arcpy.da.SearchCursor(featureClass, fields) as cursor:
    for row in cursor:
        listOfValues.append(row[0])

 

Then you can convert the list to a set.

 

# set() to convert list to set
set_of_values  = set(listOfValues)

 

 

Sets can be subtracted from each other to find the differences.
