Get statistics for each group (such as count, mean, etc) using pandas GroupBy?

Question

I have a data frame df and I use several columns from it to groupby:

df[\'col1\',\'col2\',\'col3\',\'col4\'].groupby([\'col1\',\'co         


        

Answer 1

Create a group object and call methods like below example:

grp = df.groupby(['col1',  'col2',  'col3']) 

grp.max() 
grp.mean() 
grp.describe()
