I'm having trouble with syntax in 10.2.1, and have have tried just about everything. With arcpy, I am attempting to access a label.expression of an ArcMap layer and modify it to:

lbl.expression = '[FIELDNAME] + "\n" + "taco"'

I can't get the "\n" part to force the rest of the expression to a new line.

    This works: lbl.expression = '[FIELDNAME] + vbnewline + "taco"'

  • @mfrancis... that is for vbscript in the field calculator. The question deals with Arcpy so python.

It's a Windows thing, use "\r\n" instead.

  • This is a good answer to assert a new line. I built a complex label expression ArcMap would crash when label condition met: [field1] + '\n' + [field2] Changing to[field1] + '\r\n' + [field2] works!

I'm guessing the parser was not changed to python, '\n' does work to force new lines within python label expressions.
