Parsing if/else logic.... not very scalable.

synchronizer.py

class ServiceSpecificSynchronizer(BaseSynchronizer):
    ...
    def pull_data(self, user, content_type):
        " Fetch data from the external service for the user and the specified content_type. "
        response = self.client.read(user, content_type)
        
        # Parse based on content type
        if isinstance(content_object, SomeModel):
            ... parse this data like so ...
            ... create/update content object on our side ...
        if isinstance(content_object, AnotherModel):
            ... parse this data like so ....
            ... create/update content object on our side ...
