is reclassify from the spatial analyst toolset available at the python command line?

Hi!
I'm trying to batch a bunch of files and have the following code:
arcpy.ReclassByASCIIFile_sa("D:/DATA/ILLINOIS/RFP_Landcover/Raster/chi_U19","C:/Users/Ams/Documents/SUM2011/recMap_chi_highres.txt","D:/DATA/ILLINOIS/RFP_Landcover/Raster/Reclass/Chi_U19_rc","DATA")
arcpy.ReclassByASCIIFile_sa("D:/DATA/ILLINOIS/RFP_Landcover/Raster/chi_U20","C:/Users/Ams/Documents/SUM2011/recMap_chi_highres.txt","D:/DATA/ILLINOIS/RFP_Landcover/Raster/Reclass/Chi_U20_rc","DATA")
...

I got the "code" from running it for one file and then using the "copy as python snippet" so it should work
but I get this error:
Runtime error <type 'exceptions.AttributeError'>: 'module' object has no attribute 'ReclassByASCIIFile_sa'

and when I try to get to the spatial analyst reclass tool in the command line by typing
arcpy.reclass only the ones from the 3D toolbox are available?

Does anyone know what I am doing wrong? should I just use the 3D ones?

Any assistance is appreciated.
Amelie

PS Yes, I have checked that my spatial analyst toolbox is activated

I just used the reclassify_3d and that worked - I don't know why reclassify_sa is not available but as long as they both do the same thing I guess it's OK.
Is there any major difference between the 2?

In arcpy there is a seperate sub-module for doing Spatial Analyst stuff... Try this:

arcpy.sa.ReclassByASCIIFile(blah, blah)

Other than different licensing requirements, I don't belive there is a differnce between these tools - I could be wrong though.

That worked!! Thanks a lot. I do wonder still what the difference between the two is...

The sa toolbox in arcpy behaves slightly different than other tools to support the Raster object and map algebra natively.

to find out about sa functionality, simply get its help
>>> from arcpy import sa
>>> help(sa.ReclassByTable)

Is there a difference between using reclass in spatial analyst versus 3d?

Sounds like in "backend" processing methodology: yes, in outcome: no.
