how to execute an python arcsript

System: ArcGIS 9.3

Problem

I want to use a code to split rows using a script downloaded from arcscript. (attached)
However, an error message showed that

"AttributeError: Object: Tool or environment <SplitByAttribute> not found"

Please kindly advise modification on the following code and thank you.

The error sugests that the toolbox you added
gp.AddToolbox("C:/Program Files/ArcGIS/ArcToolBox/Toolboxes/Split rows.tbx")
does not contain SplitByAttribute tool.

You can access this toolbox and tool in any location on your computer like:
gp.AddToolbox(r"C:\Temp\AdditionalAnalysis\Additional Analysis - Generic Tools.tbx")
The Script folder has to be in the same parent folder as .tbx toolbox.

Moreover, you can add toolbox alias (which is analysis2 in this case) to tool name:
gp.SplitByAttribute_analysis2(...)

Thanks for the response.

However, the location of the python tool is wrong and the code based on your modification did not work.
(The tool works well using arcGIS Desktop).

Please kindly advise how to make the source location of the python code correct.
Thank you.
(not File "H:\python_p\python_code\split_row_0717.py", should be File "C:\Program Files\ArcGIS\ArcToolbox\Scripts\SplitFC.py")
(I changed the source location using ArcGIS Desktop and ArcCatalog but did not work.)

The error message is as followed:

Traceback (most recent call last):
File "C:\Python25\Lib\site-packages\pythonwin\pywin\framework\scriptutils.py", line 310, in RunScript
exec codeObject in __main__.__dict__
File "H:\python_p\python_code\split_row_0717.py", line 46, in <module>
gp.SplitByAttribute_Analysis2(fc, fieldName, outWorkspace, fieldName)
AttributeError: Object: Tool or environment <SplitByAttribute_Analysis2> not found

Unzip the AdditionaAnalysis.zip to some folder.
Don't touch any files in unzipped folder.
Then just reference whole toolbox with tool of interest.

For location like in this image:
[ATTACH=CONFIG]16155[/ATTACH]
the reference path will be:
gp.AddToolbox(r"C:\Temp\AdditionalAnalysis\Additional Analysis - Generic Tools.tbx")

Thank you for the response.

I modified the code and copied the unzipped folder to the ArcToolbox folder.

# Add a toolbox with a model to the geoprocessor and set the workspace
gp.AddToolbox("C:/Program Files/ArcGIS/ArcToolBox/Toolboxes/AdditionalAnalysis/Additional Analysis - Generic Tools.tbx")

However, the same error still existed.

That's strange.
When you browse in ArcCatalog to this toolbox, do you see something like this:
[ATTACH=CONFIG]16182[/ATTACH]

Can you run SplitByAttribute tool (which alias is Split Feature Class By Attribute) from ArcCatalog?

Re: how to execute an python arcsript

Yes, the tool exists as the same of your picture.
Also, it works in ArcCatalog.

Thank you again.

System: 9.3
Windows: vista

Problem: I am using the following code to execute a tool to split row in the shapefile in attached test1.
It ran smoothly without errors but no outcome appeared.
The tool is also attached as AdditionAnalysis.

Please kindly advise any improvement and thank you in advance.

Finally, I made my own code.
