我没有检查以下编译器，但看起来应该如下.如果您发现需要更改的内容并尝试对其进行编译，请有人编辑此答案:

I didn't check wheter or not the following compiles, but it should look like what follows. Please someone edit this answer if you find something to change and tried to compile it:

class BaseDataRepository(ABC): 

    @abstractmethod
    def get_all_ids(self) -> List[int]: 
        pass

    @abstractmethod
    def get_data_from_id(self, _id: int) -> object: 
        pass

class InMemoryDataRepository(BaseDataRepository): 
    def __init__(self, ids, data): 
        self.ids: List[int] = ids
        self.data: Dict[int, object] = data

    def get_all_ids(self) -> List[int]: 
        return list(self.ids)

    def get_data_from_id(self, _id: int) -> object: 
        return self.data[_id]

class ConvertIDsToLoadedData(BaseStep): 
    def _handle_transform(self, data_container: DataContainer, context: ExecutionContext): 
        repo: BaseDataRepository = context.get_service(BaseDataRepository)
        ids = data_container.data_inputs

        # Replace data ids by their loaded object counterpart: 
        data_container.data_inputs = [repo.get_data_from_id(_id) for _id in ids]

        return data_container, context

context = ExecutionContext('caching_folder').set_service_locator({
    BaseDataRepository: InMemoryDataRepository(ids, data)  # or insert here any other replacement class that inherits from `BaseDataRepository` when you'll change the database to a real one (e.g.: SQL) rather than a cheap "InMemory" stub. 
})
