Informações Adicionais

This is a known behavior. The additional quotes are needed to make sure the Python window reads the field 'FID' and not a variable in a list.

Solução Provisória

The additional quotes are needed to properly form the string to be set as the expression. Without them it will not read 'FID' as a field. Instead, the method inteprates as the user is trying to use a variable in a list, because that is what that means in a Python interpreter. In the expression dialog, it does not expect the additional quotes because the Python parser understands that the brackets around a word indicate a field. Use triple quotes around the expression to maintain the full string: layer.labelClasses[0].expression = ''' "<CLR red='255'><FNT size = '17'>" + [OBJECTID] + "</FNT></CLR>" '''
