df =pd.read_csv("/content/sample_data/netflix_titles.csv",index_col=0)

splitters = df['director'].apply(lambda x: str(x).split(',')).tolist()

df_director = pd.DataFrame(splitters,index=df['title']).stack()

df_director3 = pd.DataFrame(df_director)

df_director3.reset_index()

df_directors = df_director3[['title',0]]

df_directors

KeyError：“['title']不在索引中”

我假设您希望将控制器名称拆分为逗号，并使用标题和每个控制器名称创建一个新的 Dataframe 。
尝试在stack（）之后使用reset_index（）使索引再次成为常规列，然后使用rename（）给予新列命名：

这里，我们将列 level_1（由stack（）创建）重命名为 director_index，将列0重命名为 director。最后，我们只选择 df_directors 中我们想要的列（title 和 director）。
假设输入为：

{'title': ['Stranger Things', 'The Crown', 'House of Cards'],
    'director': ['Matt Duffer, Ross Duffer', 'Peter Morgan', 'Beau Willimon, David Fincher, Joel Schumacher']}

输出应该如下所示：

顺便说一句，尽量避免将数据作为图像发布。
