Python Script - Overwriting records

Hi @trungn1993,

Do you want to create a new feature for each record, or do you you want to create list attributes on the feature?

How about both :)?

Different processes for each.

I want to create list attributes on the feature.

This is the one way you can create a list on an attribute

import fme
import fmeobjects

def processFeature(feature):
    list = ['apple','banana','pear']
    for i, val in enumerate(list):
        feature.setAttribute('list{'+str(i)+'}.fruit',val)

Don't forget to enter the list attribute in the python caller under Attributes to Expose

In addition to the reply by @egomm, here's a solution for creating one feature for each element in a Python list:

import fme
import fmeobjects
 
class processFeature(object):
    def input(self, feature):
        list = ['apple','banana','pear']
        for i, val in enumerate(list):
            new_feature = feature.clone()
            new_feature.setAttribute('list_value', val)
            self.pyoutput(new_feature)

This will create a copy of the incoming feature(s) for each element in the list, adding a new attribute "list_value".
