我正在尝试将2个数据框与该行合并。
recommendations_df = recommendations_df.merge(anime_df, how = 'left',
left_on = 'name',
right_on = 'name')[['episodes',
'user_rating',
'anime_id',
'genre',
"Score",
"name",
"type",
"members"]]
键“名称”在两个数据帧中，但是当我运行代码时，它可以工作，但是返回初始数据帧（命令），而没有我想要的列（片段...等）。
recommendations_df看起来像
name Score
0 Shinreigari Ghost Hound 0.946970
2 Wonderful Rush 0.882727
3 Saber Marionette J to X 0.836957
5 Hyouka 0.812808
6 Super Lovers 0.811879
和anime_df
