Error saving object from python script using GetParameterAsText

badrinathkar — Mon, 17 May 2021 04:41:25 GMT

I have made pythan script tool in which the

workspace + "/Data.shp" is sucessfully saving the files as here:

>>> import arcpy
... import os
... import sys
... from arcpy import env
... arcpy.env.overwriteOutput = True
###########################################
... InFc = arcpy.GetParameterAsText(0)
... workspace= arcpy.GetParameterAsText(1)
... Output_Data_shp = workspace + "/Data.shp"
... Output_Table_dbf = workspace + "/Table.dbf"
... # Process: Table Select
... arcpy.TableSelect_analysis(InFc, Output_Table_dbf, "")
... # Process: Dissolve
... arcpy.Dissolve_management(InFc, Output_Data_shp, "", "", "MULTI_PART", "DISSOLVE_LINES")

But when I allow users to define the path, the tools fails to execute. For this I used following code:

>>> import arcpy
... import os
... import sys
... from arcpy import env
... arcpy.env.overwriteOutput = True
###########################################
... InFc = arcpy.GetParameterAsText(0)
... Output_Data_shp = arcpy.GetParameterAsText(1)
... Output_Table_dbf = arcpy.GetParameterAsText(2)
... # Process: Table Select
... arcpy.TableSelect_analysis(InFc, Output_Table_dbf, "")
... # Process: Dissolve
... arcpy.Dissolve_management(InFc, Output_Data_shp, "", "", "MULTI_PART", "DISSOLVE_LINES")

For information, I am running the Python script inside a normal toolbox (i.e. not inside a python toolbox). I have defined the data types correctly under the Parameters tab of the script. Although python is quite new to me and I am not trained enough to implement codes into the script to detect errors, I think the GetParametersAsText defines the directory with Single Backslash (/) which hinders the tool to execute.

Any suggestions to solve the issue? Thanks in advance.

for the 2nd parameter (your workspace), do you have it defined as a "folder" ?

and did you try raw encoding

Output_Data_shp = r"{}\\Data.shp".format(workspace) # raw encoding

I prefer to let the os module do any path wrangling for me.

import os Output_Data_shp = os.path.join(workspace, "Data.shp") Output_Table_dbf = os.path.join(workspace, "Table.dbf")

My apologies. I had done a horrible mistake in posting the 2nd code (actually I posted the same code in both places). Please consider the following:

workspace= arcpy.GetParameterAsText(1)

workspace + "/Data.shp"

workspace + "/Stat.dbf" is working fine.

Tool fails to execute when I allow users to save the files using the GetParameterAsText:

Output_Data_shp = arcpy.GetParameterAsText(1)
Output_Table_dbf = arcpy.GetParameterAsText(2)

I have defined workspace as workspace data type.

workspace .... should be defined as a "folder" in your toolbox. Double backslashes as in my examples would be preferable (or use the os module as David suggested), you don't want to mix back and fore slashes.

It would help if you posted the actual error message. But a wild stab in the dark is that you have an undeclared variable.. You declare the dbf as Output_Table_dbf and then attempt to use Output_Stat_Table_dbf
