Error Executing tool: ArcPY

Question

I am stuck with a code due to a RunTimeError: Object: Error in Executing tool and I really can't find the mistake. The code is

# Now, the script for "Adding Surface Info" to the network, using the raster with MAX MEAN defined just above
# Set the raster of input, on the basis of the MAX MEAN
inSurface = "C:/B3061239/!!! WORK !!!/RAS_for_maxmean/", NameRasList[MEANlist.index(max(MEANlist))]
# NOTE that NameRasList[MEANlist.index(max(MEANlist)) has been calculate before
method = "BILINEAR"
if inSurface:
 print "Got inSurface"
# Create list of feature classes
fcList = arcpy.ListFeatureClasses()
print str(len(fcList))
# Process: Add Surface Information
if fcList:
 print "Got featureclasses"
 for fc in fcList:
 desc = arcpy.Describe(fc)
 print desc.name
 # Determine if the feature is 2D
 #if not desc.hasZ:
 #if desc.shapeType == "Polygon":
 # Desired properties separated by semi-colons
 #Prop = "Z_MIN;Z_MAX" 
 #elif desc.shapeType == "Point":
 #Prop = "Z"
 #elif desc.shapeType == "Multipoint":
 #Prop = "Z_MIN;Z_MAX;Z_MEAN"
 #elif desc.shapeType == "Polyline":
 #Prop = "LENGTH_3D"
 # Execute AddSurfaceInformation
 arcpy.ddd.AddSurfaceInformation(fc, inSurface, "Z_MAX", method, "", "1", "0", "NO_FILTER")
print "Completed adding surface information."

• Tristan Forward: Can you please edit you post to use code formatting? It's very hard to read currently as a wall of text.
• Neil Ayres: Is this a real path to some data : inSurface = "C:/B3061239/!!! WORK !!!/RAS_for_maxmean/"? I would certainly get rid of the spaces and "!!!" stuff. If you want a real answer for this, start by telling us ArcGIS version etc and perhaps provide the code and actual error message you are getting.
• Tristan Forward: Try changing inSurface = "C:/B3061239/!!! WORK !!!/RAS_for_maxmean/" to "inSurface = r"C:/B3061239/!!! WORK !!!/RAS_for_maxmean/" The change is the raw string "r" its hard to see the change.
• user2856: @TristanForward raw string is not required as the string variable does not contain any backslashes.
• user2856: Can you edit your post to add the entire error traceback, not just the final error message.

Consider using an error handler to locate the source of the error....

try:
 import sys, traceback
 #YourCodeHere
except arcpy.ExecuteError: 
 print "error"
 msgs = arcpy.GetMessages(2) 
 arcpy.AddError(msgs) 
 print msgs
except:
 print "error"
 tb = sys.exc_info()[2]
 tbinfo = traceback.format_tb(tb)[0]
 pymsg = "PYTHON ERRORS:\nTraceback info:\n" + tbinfo + "\nError Info:\n" + str(sys.exc_info()[1])
 print pymsg + "\n"
