Trying to extract a dependency

enricher.py

def add_foos(stuff):
    for thing in stuff:
        thing['foo'] = float(thing['id']) * 2.0
    return stuff

class ConnectorThing(object):
    result_enricher = add_foos
    def get_results(self):
        # do something
        bar = [{'id': 1}, {'id': 2}, {'id': 3}]
        bar = self.result_enricher(bar)
        
ConnectorThing.get_results()
