# Python Script Example
import fmeobjects

class UpdateCounter(object):
    def __init__(self):
        self.counter = {}
       
    def input(self, feature):
        update = feature.getAttribute('UPDATE')
        if update:
            for v in [s.strip() for s in str(update).split(';')]:
                self.counter[v] = self.counter.setdefault(v, 0) + 1
       
    def close(self):
        for v in self.counter.keys():
            feature = fmeobjects.FMEFeature()
            feature.setAttribute('value', v)
            feature.setAttribute('count', self.counter[v])
            self.pyoutput(feature)
