I want to convert a large number of different shp polygons to raster in ArcGIS 10.1, using an existing field column "class" for the new raster classes. I am not very fluent in python but I thought this would work, and it doesn´t:
# Import arcpy module
import arcpy
... # Local variables:
... project_input = "D:\\RESEARCH_PROJECTS\\NORD-STAR\\AMAZONIA\\1-RAW_DATA\\INPE\\PRODES DIGITAL\\2004\\"
... raster_output = "D:\\RESEARCH_PROJECTS\\NORD-STAR\\AMAZONIA\\1-RAW_DATA\\INPE\\PRODES DIGITAL\\2004\\convert\\"
... # List features
... arcpy.env.workspace = project_input
... fcList = arcpy.ListFeatureClasses()
... # Loop
... for featureClass in fcList:
... # Output
... raster_outputpath = raster_output + featureClass
...
... # Process: Polygon to Raster
... arcpy.PolygonToRaster_conversion(featureClass, "CLASS", raster_output, "CELL_CENTER", "NONE", "30")
... print "finished polygon to raster"
...
Runtime error Traceback (most recent call last): File "", line 20, in File "c:\program files (x86)\arcgis\desktop10.1\arcpy\arcpy\conversion.py", line 2436, in PolygonToRaster raise e ExecuteError: ERROR 999999: Error executing function. Failed to execute (PolygonToRaster).
The script actually calls the first polygon, but that is it:

The problem is that your code defines raster_outputpath but you try to save the raster in raster_output.
