列出一个 dataframe 组织成几个月,具有 nunique 和 Max() 的其他功能 [关闭]

[英]Listing a dataframe organised into months with nunique and Max() of other features [closed]

页面总赞数 类别 发布月
139441 2 12
139441 2 12
139441 3 12
139441 2 12
139441 2 12

我有一张像上面这样的桌子。 我试图在每个月的列表中获得每个类别 (1-3) 的最高页面总赞数,写成 1-12

         .apply(list)
         .groupby(level=0)
         .apply(np.cumsum)
         .apply(lambda x: len(set(x)))
         .reset_index(name='cumulative_module_count'))```


gives me a list without the grouping nor maximum likes

My result should be a multi-dimensional list example:

[Month, 1, Category, 1, Page total likes,139441],[Month, 1, Category, 2, Page total likes,124958],[Month, 1, Category, 3, Page total likes,109441],[Month, 2, Category, 1, Page total likes,129441],[Month, 2, Category, 2, Page total likes,199441],...[Month, 12, Category, 3, Page total likes,129441]

The above shows a list where each month(1-12) expressed for each Category (1-3) identifying the max likes for that given category in that month.
