Word spacing in labels

[AmyKlug]

I've got an easy one for you. How do you add a space between field names in a feature class label in python using lblclass.expression? I was using [Field1]& " " &[Field2] and can't find the python method.

Thanks

I am not sure why you are getting errors.  I just tested this as a script tool and got no errors and it worked as expected.  You do not have to manually set up the expression to be Python.  It is designed to read JavaScript, VB, or Python.  This code worked as a script tool taking 2 field parameters and an input layer:

import arcpy  # Params lyr = arcpy.GetParameterAsText(0) fieldA = arcpy.GetParameterAsText(1) fieldB = arcpy.GetParameterAsText(2)  # Do stuff mxd = arcpy.mapping.MapDocument("CURRENT") layer = arcpy.mapping.ListLayers(mxd, lyr)[0] if layer.supports("LABELCLASSES"):     for lblclass in layer.labelClasses:         lblclass.showClassLabels= True         lblclass.expression= '[%s] + " " + [%s]' %(fieldA,fieldB)         layer.showLabels= True         arcpy.RefreshActiveView()

OR I also got it to work as a multi-value field parameter:

import arcpy  # Params lyr = arcpy.GetParameterAsText(0) fields = arcpy.GetParameterAsText(1).split(';')  # Do stuff mxd = arcpy.mapping.MapDocument("CURRENT") layer = arcpy.mapping.ListLayers(mxd, lyr)[0] if layer.supports("LABELCLASSES"):     for lblclass in layer.labelClasses:         lblclass.showClassLabels= True         lblclass.expression= '[%s] + " " + [%s]' %(fields[0],fields[1])         layer.showLabels= True         arcpy.RefreshActiveView()

EDIT: I just fixed a small quote error
