Cannot save any geoprocessing result with ArcPy?

Question

I have a problem to get the code below running as a python script tool in ArcGis 10.2.2. I always get this error Message: AttributeError: ResultObject: Get attribute save not found
The tool help clearly says that there is a .save function. What am I doing wrong?

# Import arcpy module
import arcpy


# Check out any necessary licenses
arcpy.CheckOutExtension("spatial")

inRaster = arcpy.GetParameterAsText(0)
DGM = arcpy.Raster(inRaster)

# Process: Fill
Fill_DGM = arcpy.gp.Fill_sa(DGM, "Fill_DGM", "")
Fill_DGM.save("F:/Desktop/test/Filled")

Answer 1

# Import arcpy module
import arcpy
from arcpy.sa import * 


# Check out any necessary licenses
arcpy.CheckOutExtension("spatial")

inRaster = arcpy.GetParameterAsText(0)
DGM = arcpy.Raster(inRaster)

# Process: Fill
Fill_DGM = Fill(DGM)
Fill_DGM.save("d:/scratch/Filled")

Answer 2

I realise this already has an accepted answer, but for the benefit of other users, here is why your code in its original form failed.

Your code failed because you were calling a save function on a Result object. Results objects do not have a save function. They have a saveToFile function. This saves information about tool execution, parameters, messages and output. This is not what you intended to do.

This would have sufficed:

arcpy.env.workspace  = r"c:\scratch.gdb"
Fill_DGM = arcpy.gp.Fill_sa(DGM, "Fill_DGM", "") #this creates a raster called FILL_DGM in the specified workspace.

Things to note:

• The variable Fill_DGM above is a Result object
• Fill_DGM.getoutput(0) # this returns full path to FILL_DGM raster: c:\scratch.gdb\FILL_DGM
• No need for FILL_DGM.save(path_to_disk) # this would fail as explained above.
• spatial-analyst tools accessed via arcpy.sa.InsertToolNameHere return Raster Objects whereas spatial-analyst tools accessed via arcpy.gp.insertToolNameHere_sa return Result Objects.
• The type of object returned dictates which functions are available to you.
