I have a simple example python script below that accepts an address and is trying to return the XY.

My plan is to take this python script and create a tool and publish this to ArcGIS Server as a service 

I can then call the service and pass it the address parameter.  THe code will run and set a variable to the XY location of the geocoded address.  Great everything works....

How do I get that XY back to the user that is passing the address parameter?

import arcpy

# Geting user input for address
searchAddress = arcpy.GetParameterAsText(0)

# SEARCH PARAMETERS FROM SERVICE
print "passed search address: " + searchAddress
print ""

# GEOCODERS
geoCodeUrl = "https://geocode.arcgis.com/arcgis/rest/services/World/GeocodeServer/findAddressCandidates"

def singleAdressGeocode(address, geoCodeUrl, outSR = "26917"):
  ##clean up the address for url encoding
  address = address.replace(" ", "+")
  address = address.replace(",", "%3B")

  #send address to geocode service
  lookup = requests.get(geoCodeUrl + "?SingleLine=" + address + "&outSR=" + outSR + "&maxLocations=1&f=pjson")
  #get results to variable
  data = lookup.json()
  
  if data["candidates"]:
    return data
  else:
    ##no results
    return "Address not geocoded: " + address

# CALL GEOCODER
geocodeResult = singleAdressGeocode(searchAddress, geoCodeUrl)

# GET RESULTS
addressResult = geocodeResult["candidates"][0]["address"]
coordinateX = geocodeResult["candidates"][0]["location"]["x"]
coordinateY = geocodeResult["candidates"][0]["location"]["y"]
strcoordinateX = str(coordinateX)
strcoordinateY = str(coordinateY)

# SHOW RESULTS
print "gecode result: " + str(geocodeResult)
print "-------------------"
print "geocoded address: " + addressResult
print "-------------------"
print "X coordinate: " + str(coordinateX)
print "-------------------"
print "Y coordinate: " + str(coordinateY)
print "-------------------"

I set an output parameter in the python tool and then passed the value as such

I had 3 input parameters and set the 4th to an output parameter...dont forget the index starts at 0 so the 4th would be 3

msg =("testing result value")
arcpy.AddMessage(msg)
resultMsg = msg
arcpy.SetParameterAsText(3, resultMsg)

Do I have to add an out parameter to the toolbox tool that is running the script?

if I have to do that what do I put in the python script to write the values to the output parameter?
