Python Script Help - Spaces in filename

JamesMitchell — Wed, 23 May 2012 11:13:44 GMT

Hello,

Please can somebody provide some advice?

I am using the code below in a script to add a field to multiple shapefiles, however when the filename or file location contains spaces it does not work. I get the error message "Input Table: xxxxx does not exist or is not supported"

I think it must have something to do with the LayersList = string.split(arcpy.GetParameterAsText(0),";") line, but as i am new to Python i do not know how to correct it.

It will be greatly appreciated if someone can help me.

Thank you.

James

import arcpy, os, string

#Read input parameters from script tool
LayersList = string.split(arcpy.GetParameterAsText(0),";")

# Process: Add Field
for Layer in LayersList:
arcpy.AddField_management(Layer, "DUP", "DOUBLE", 9, "", "", "Dup", "NULLABLE")

Thank you ver much for the quick response.

I have tried this and it still has the same error.

The input parameters are shapefiles.

Thanks

You should remove any spaces from your shapefile names.

Thank you,

The shapefiles are in different locations. When i save them into a folders without any spaces it works but when i move them into a folder location with spaces it no longer works.

Thanks for your input.

Spaces in path names are not supported either for some functions.

It's because arcpy is wrapping single quotes around the file path.

print repr(Layer) >>> u"'C:\\WorkSpace\\test workspace\\test.shp'"

This works:

import arcpy, os  #Read input parameters from script tool LayersList = arcpy.GetParameterAsText(0).split(";")  # Process: Add Field for Layer in LayersList:     arcpy.AddMessage(repr(Layer))     arcpy.AddField_management(Layer.strip("'"), "DUP", "DOUBLE", 9, "", "", "Dup", "NULLABLE")

Thank you, this helped me figure out how to remove the extra quotes from my layer files that had spaces.
