部分输出如下: An abstract class representing a :class:`Dataset`. All datasets that represent a map from keys to data samples should subclass it. All subclasses should overwrite :meth:`__getitem__`, supporting fetching a data sample for a given key. Subclasses could also optionally overwrite :...
例如,datasetObj.varlist['numvar']访问与变量numvar关联的Variable对象。 请参阅主题变量类 (Python)以获取更多信息。 您可以使用与数据集关联的CaseList对象的append(或insert) 方法将观测值添加到数据集。 可从Dataset对象的cases属性访问CaseList对象,如datasetObj.cases中所示。 请参阅主题CaseList Class (Python...
accessible from theVariableListobject. For example,datasetObj.varlist['numvar']accesses theVariableobject associated with the variablenumvar. See the topicVariable Class (Python)for more information.
