please help: label expression

NidaJackson — Wed, 22 Jul 2015 18:31:32 GMT

Hi Everyone,

I need some help. I am not a python expert nor a programmer but I am a GIS user. Trying to learn python scripting for now.

This is what I am trying to make an expression in python:

I try this:

def FindLabel ( [POLY_ID], [EV_CODE], [STAND_CONDITION_CODE] 😞

return "<BOL><UND>" + " " + [POLY_ID] + " " + "</UND></BOL>" + '\n' + [EV_CODE] + "-" + [STAND_CONDITION_CODE]

And I want,

if [EV_CODE] and [STAND_CONDITION_CODE] is None:

return "?"

Is anyone can help me create an expression for this label?

Your responses is highly appreciated.

Thank you,

nidz

It should be something like this (untested):

def FindLabel ( [POLY_ID], [EV_CODE], [STAND_CONDITION_CODE] ):
  if [STAND_CONDITION_CODE]:
      SCC = [STAND_CONDITION_CODE]
  else:
      SCC = '?'
  if [EV_CODE]:
      EC = [EV_CODE]
  else:
      EC = '?'
  return "<BOL><UND>" + "  " +  [POLY_ID] + "  " +  "</UND></BOL>" + '\n' + EC + "-" + SCC
