It would be tremendously helpful if someone could post a sample python toolbox (pyt) that accepts a dummy input parameter or two, and returns "hello world of pyt gp services!"  I figure with that template, I could do my own gp routines during the execution, and replace the "hello world" with the results of my gp work.  I don't need any geometry returned, just text. The use case here is to return nearby addresses from an input lat/long. This code fails: import arcpy import os class Toolbox(object):     def __init__(self):         self.label = "Get Nearby Addresses"         self.alias = ""         # List of tool classes associated with this toolbox         self.tools = [GetNearbyAddresses] class GetNearbyAddresses(object):     def __init__(self):         self.label = "Get Nearby Addresses"         self.description = "Get Nearby Addresses within a buffer."         self.canRunInBackground = False     def getParameterInfo(self):                 params = []                 param0 = arcpy.Parameter(             displayName = "Latitude",             name = "lat",             datatype = "Double",             parameterType = "Required",             direction = "Input")         params.append(param0)                 param1 = arcpy.Parameter(                     displayName = "Longitude",                     name = "lon",                     datatype = "Double",                     parameterType = "Required",                     direction = "Input")         params.append(param1)                 param2 = arcpy.Parameter(             displayName = "Buffer Distance",             name = "distance",             datatype = "Long",             parameterType = "Required",             direction = "Input")         params.append(param2)                 param3 = arcpy.Parameter(                     displayName = "Address List",                     name = "addresses",                     datatype = "GPString",                     parameterType = "Derived",                     direction = "Output")         params.append(param3)                return params     def execute(self, parameters, messages):         try:             arcpy.env.workspace = r'E:\gis\default.gdb'             arcpy.env.overwriteOutput = True                         lat = parameters[0].valueAsText             lon = parameters[1].valueAsText             distance = parameters[2].valueAsText                         #inpoint = arcpy.Point(X=lon, Y=lat)             #ptGeometry = arcpy.PointGeometry(inpoint, arcpy.SpatialReference(4326))             #arcpy.Buffer_analysis(ptGeometry, 'buffer', distance + ' FEET', \             #                      "FULL", "ROUND", "NONE", "")             #get intersecting addresses here                         parameters[3].value = 'a nice list of addresses!'  # I need this from a gp service!                         return                 except Exception, ErrorDesc:             sErr = "ERROR:\n" + str(ErrorDesc)             messages.addErrorMessage(sErr)         return ...
