Failed to execute (RastertoPolygon) Syntax error at or near symbol SPACE

I'm converting series of raster to polygon using RastertoPolygon in arcpy.

#import the module import arcpy from arcpy.sa import * from arcpy import env arcpy.CheckOutExtension("Spatial") env.overwriteOutput = True #set the workspace env.workspace = r"C:\thesis\for sampling\sampling_outputs\raster_per_biogeoregion" #Get a list of rasters and convert to shapefile for raster in arcpy.ListRasters("*Luzon_*.tif", "TIF"): print raster #check the presence of rasters arcpy.RasterToPolygon_conversion(raster, raster.replace("tif", "shp"), "NO_SIMPLIFY") print "Finish converting all the rasters to polygon"

After several checks on the syntax, formatting, I've always been stuck with this error:

Traceback (most recent call last): File "C:\Users\brentiebark\Dropbox\Python Scripts and mxds\batch_convert_raster_to_polygon_simple.py", line 14, in <module> arcpy.RasterToPolygon_conversion(raster, raster.replace("tif", "shp"), "NO_SIMPLIFY") File "C:\Program Files (x86)\ArcGIS\Desktop10.1\arcpy\arcpy\conversion.py", line 178, in RasterToPolygon raise e ExecuteError: ERROR 010328: Syntax error at or near symbol SPACE.

Just a guess, can you remove spaces from your directory path and try again.

Hi Robert Beno ,

Neil Ayres suggestion might be right. Using spaces and special characters in paths might cause problems, especially when you use rasters.

When you post code, could you please use syntax highlighting for your code (see: Posting Code blocks in the new GeoNet ). If I copy your code and paste it into PyScripter it points out an error on line 14 where you are missing a space to indent the line and align the code with line 13.

Other observations:

you import the sa module, but you don't use it
you check out a spatial analyst extension but you don't use it
if the extension tif of a raster would be TIF, it will fail

Yes, it looks to me like line 14 is not indented properly. It should be consistent with the indenting for the print line above it.
