Pandas: Passing a list through describe()

Question

I am trying to describe() a column from df but for every unique value in another column.I have the df:

id revenue country 
1  128     at
2  130     de
3  132     de
4  134     hu
5  136     at
6  138     at 
7  140     hu

I want to pass this :

df[df['Country']=='cz'].net_revenue.describe(percentiles=[0.2,0.4,0.6,0.8,0.9,0.95,0.99,0.999])

But for every unique value in the column Country.

Answer 1

Use groupby.describe:

out = (df.groupby('country')['revenue']
         .describe(percentiles=[0.2,0.4,0.6,0.8,0.9,0.95,0.99,0.999])
      )

Output:

         count   mean       std    min    20%    40%    50%    60%    80%    90%    95%     99%    99.9%    max
country
