应用groupby后从网上论坛中获取特定元素-PANDAS [英] Get specific element from Groups after applying groupby - PANDAS

问题描述

我通过以下方式将一个数据帧中的总和数据分组:

I have grouped sum data in a dataframe, by the following:

groups = df.groupby(['name'])

现在，我可以通过groups.head(2)来获得组的头，它给出了前两行.

Now I can get the head of the groups by groups.head(2) which gives the first two rows.

但是如何获得一个具有特定名称的群组?即，如果我要使用组名称为"ruby​​"的单个组，则不能只做group ['ruby']

But how do I get a group by a specific name? i.e. if I want the single group where the group name is 'ruby', I can't just do groups['ruby']

推荐答案

怎么样:

groups.get_group('name')
