penn state four exercise

#You have a point feature class of graffiti incidents and a polygon feature class of patrol zones with some empty attributes 
#already created for you. You must write a script that updates the attributes of the patrol zones with:

#The number of graffiti incidents falling within the patrol zone. This is an integer that goes in the INCIDENTS field.
#The priority ranking for the patrol zone. This is a string that goes in the PRIORITY field. You will derive this string using some simple math that compares the number of incidents in the zone with the area of the zone

import arcpy
arcpy.env.overwriteOutput = True
 
PatrolZones = "D:\\WCGIS\\Geog485\\Lesson3PracticeExerciseB\\Washington.gdb\\CityBoundaries"
Graffiti = "D:\\WCGIS\\Geog485\\Lesson3PracticeExerciseB\\Washington.gdb\\ParkAndRide"
GraffitiField = "INCIDENTS"
ZoneField = "PRIORITY"

valueList = [] # array to hold list of values collected
valueSet = set() # set to hold values to test against to get list
rows = arcpy.SearchCursor(inputTable) # create search cursor
 
# iterate through table and collect unique values
for row in rows:
    value = row.getValue(field)
 
    # add value if not already added and not current year
    if value not in valueSet:
        valueList.append(value)
 
    # add value to valueset for checking against in next iteration
    valueSet.add(value)
 
# return value list
valueList.sort()
#return valueList
