I keep getting this error from this line.
arcpy.CreateFishnet_management(os.path.join(Output_Folder, "Full_Grid.shp"), str(NAR_U9.extent.XMin) + " " + str(NAR_U9.extent.YMin), str(NAR_U9.extent.XMin) + " " + str(NAR_U9.extent.YMin + 10), Cell_Size_Width, Cell_Size_Height, "0", "0", str(NAR_U9.extent.XMax) + " " + str(NAR_U9.extent.YMax), "NO_LABELS", NAR_U9, "POLYLINE")
I can't seem to find anything online about what the 'unicode' part means. I'm giving it specific values for the coordinates for the corners so I don't understand where it's looking for an extent attribute.
