ArcToolbox scripts behave differently then the hard-coded versions.

I made a four color map algorithm for Python. When I execute the script in PythonWin, Komodo, or Idle, with the path to the feature class hard-coded into the script, things run fine. I know the syntax is correct. Once I add the script to ArcToolbox it throws an error (error message posted below). The error occurs at this line.

if (geometry1.touches(geometry2) or geometry1.overlaps(geometry2)) and counter != counter1:

File "E:\SCRIPT~1\MINIMU~1\minimumpolygoncolor.py", line 46, in <module>
if (geometry1.touches(geometry2) or geometry1.overlaps(geometry2)) and counter != counter1:

Error Info:
'unicode' object has no attribute 'touches'
ArcPy ERRORS:

I also developed a tool to remap data paths in an mxd. Again, things run fine if I post the code into the Python window. All the broken links are fixed. When I convert this tool to a Toolbox script, the paths get updated...and then removed from the mxd.

Does anyone know why a script would act differently once they are brought into ArcToolbox?

Gerry,

you probably need to post more of your code. The error message you are receiving indicates that the geometry is not actually an object - just a string (some text), in this case a Unicode string, which is how the parameters from Arc are brought in...

You can do some testing with arcpy.AddMessage() just before the line that is failing, for example:

arcpy.AddMessage(str(geometry1)+type(geometry1))

You can then test this in both situations and check it is the same...

Here is a portion of the code that returns the error. Again, it works fine as a stand alone where it is taking the inFC as text just like the arcpy.GetParameterAsText(0)

try:
    print "go"
    import arcpy, os, sys, string, traceback, operator
    inFC = arcpy.GetParameterAsText(0)
    g1 = arcpy.Geometry()
    geometrylist1 = arcpy.CopyFeatures_management(inFC, g1)
    g2 = arcpy.Geometry()
    geometrylist2 = arcpy.CopyFeatures_management(inFC, g2)
    
    for geometry1 in geometrylist1:
        for geometry2 in geometrylist2:
            if (geometry1.touches(geometry2) or geometry1.overlaps(geometry2)):
                print "Do more stuff here..."
    print "done"
except arcpy.ExecuteError:
    msgs = arcpy.GetMessages(2) 
    arcpy.AddError(msgs) 
    print msgs
except:
    tb = sys.exc_info()[2]
    tbinfo = traceback.format_tb(tb)[0]
    pymsg = "PYTHON ERRORS:\nTraceback info:\n" + tbinfo + "\nError Info:\n" + str(sys.exc_info()[1])
    msgs = "ArcPy ERRORS:\n" + arcpy.GetMessages(2) + "\n"
    arcpy.AddError(pymsg)
    arcpy.AddError(msgs)
    print pymsg + "\n"
    print msgs

Stacy, thanks for the tip.

When I run the tool in Komodo I get this for the str(geometry1) and type(geometry 1)

<geoprocessing describe geometry object object at 0x0ECA3D28>
<class 'arcpy.arcobjects.geometries.Polygon'>
<geoprocessing describe geometry object object at 0x0ECA3D28>

In ArctoolBox I get this:

i
<type 'unicode'>

Gerry,

try putting AddMessage() comments after every operation. There is a good chance that your input isn't coming through quite as you expect it. I.e. make the top part of your code like so:

try:
    print "go"
    import arcpy, os, sys, string, traceback, operator
    inFC = arcpy.GetParameterAsText(0)
    arcpy.AddMessage(str(inFC)+str(type(inFC)))
    g1 = arcpy.Geometry()
    geometrylist1 = arcpy.CopyFeatures_management(inFC, g1)
    arcpy.AddMessage(str(geometrylist1)+str(type(geometrylist1)))
    g2 = arcpy.Geometry()
    geometrylist2 = arcpy.CopyFeatures_management(inFC, g2)
    arcpy.AddMessage(str(geometrylist2)+str(type(geometrylist2)))
