My code is not doing anything

Question

I have written a code to check if areas will be inundates when a certain value is added, the code doesn't give any errors but at the same time it does do anything. Just says running code complete, I am not even sure what the problem is. My code is here import arcpy import os, sys, traceback, shutil import numpy as np arcpy.env.overwriteOutput = True try: outputfolder = arcpy.GetParameterAsText(0) fc = arcpy.GetParameterAsText(1) inputraster = arcpy.GetParameterAsText(2) #check to see if the arcinfo license is on if arcpy.CheckExtension("Spatial") == "Available": arcpy.CheckOutExtension("Spatial") else: arcpy.AddError("Spatial analyst extension is not licensed.") sys.exit() #set the Progressor #arcpy.SetProgessor("step","Checking input requirements....",0,9,1) #Process :create an out put folder arcpy.CreateFileGDB_management(outputfolder,"output.gdb") outputgdb = outputfolder + "\output.gdb"+ os.step #create path to store raster data clippedraster = outputfolder + "clippedraster" flooded = outputfolder +"floodedarea" #check to see if the inputs are in the same projection desccs_ras = arcpy.Describe(inputraster).SpatialReference desccs_fc = arcpy.Describe(fc).SpatialReference if desccs_ras.name == "Unknown" and desccs_fc.name == "Unknown": arcpy.AddMessage("Your data does not have a defined spatial reference") else: if desccs_ras.projectionName == desccs_fc.projectionName: "" else: arcpy.AddError("The input Data should be in the same projection") sys.exit() del desccs_fc,desccs_ras #remove the areas below sea level currentRaster = arcpy.Raster(inputraster) rastertoclip = Con(currentRaster>=0,currentRaster,1) #clip the raster data to the interested zone extend arcpy.Clip_management(rastertoclip,"#",clippedraster,fc,"#","ClippingGeometry","MAINTAIN_EXTENT") clip_raster = arcpy.Raster("in_memory") areasbelow = clip_raster <= 2 areasbelow.save(flooded) md = arcpy.mapping.MapDocument("CURRENT") df = arcpy.mapping.ListDataFrames(md)[0] result = arcpy.MakeRasterLayer_management(flooded,"FloodedArea") layer = result.getOutput(0) arcpy.mapping.AddLayer(df, layer,"AUTO_ARRANGE") except: tb = sys.exc_info()[2] tbinfo = traceback.format_tb(tb)[0] pymsg = "PYTHON ERRORS: Traceback Info: " + tbinfo + " Error Info: " + \ str(sys.exc_type)+ ": " + str(sys.exc_value) + " " ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

it looks like your except creates a message "pymsg", but you aren't printing it. Because I switch a lot between the different script windows and tools, etc, I always add a simple function and call it. It may dupe the response in a python window, but it helps when switching between. fwiw def myMsgs(message): arcpy.AddMessage("{0}".format(message)) print("{0}".format(message) )‍‍‍ then call it with myMsgs("my message here, and variable if I want {0}, {1}".format(var1, var2))

I am running the code in a custom toolbox and therefore the use of the arcpy.AddMessage
