When you convert my_list to a set, Python eliminates all duplicate entries. The resulting set, unique_values, contains only the unique elements from the original list. Keep in mind that sets are unordered, so the output might not reflect the original order of elements. If order matters, you...

DataFrame.get_values(self)[source] 将稀疏值转换为稠密值后,返回一个ndarray。 从0.25.0版开始不推荐使用:np.asarray(..)或DataFrame.values()代替。 这与.values非稀疏数据相同。对于SparseArray中包含的稀疏数据,首先将其转换为密集表示。 返回值:
仔细观察,会发现 seas、trend 和 resid 三列的乘积正好等于 actual_values。 8、平稳和非平稳时间序列 平稳是时间序列的属性之一。平稳序列中的值不是时间的函数。 也就是说,平稳序列的平均值、方差和自相关性等统计特征始终为常数。序列的自相关性是指该序列与之前的值间的相关性。
