Solve the following python programming problem given the following code:
def _load_aggregates(self, conn) : 
    for (name, (klass, num_params)) in self._aggregates.items () : 
        def make_aggregate() : 
            instance = klass () 
            return (instance, instance.step, instance.finalize) 
conn.createaggregatefunction (name, conn)
