所有流派包括:
[[“动作”、“冒险”、“动画”、“儿童”、“喜剧”、“犯罪”、“纪录片”、“戏剧”、“幻想”、“黑色电影”,
我怎样才能知道哪种类型的平均评论最高,哪种类型的平均评论最低?我应该按收视率分组,然后按所有相应的体裁分组吗?
df = bigdataframe[['Action', 'Adventure','Animation', 'Childrens', 'Comedy',
'Crime','Documentary', 'Drama', 'Fantasy', 'FilmNoir',
'Horror', 'Musical', 'Mystery',
'Romance','SciFi', 'Thriller', 'War', 'Western','rating']]
gp = df.groupby('rating')
result = gp.agg(['mean'])
结果告诉我:
