python - nlargest on groupby with multiindex and multiple agg column -


stuggling apply .nlargest() groupedby data in order show largest 10 gross revenue per index[0]

groupedby data looks this:

data currently

when run:

grp_data.n_largest(10,'grossrevenue_gbp')

doesn't seem working me, full code snippet below:

tmean = lambda x :stats.trim_mean(x, 0.1)  data = data.loc[(data['yyyy'] == 2016)&(data['new_category_id'] != 0)]  grp_data = data.groupby(['new_category','cdi_cus_nm'])['grossrevenue_gbp', 'ordercount', '% rev',  'movc_gbp',  'average order size'] .aggregate({'grossrevenue_gbp':np.sum, 'ordercount':np.sum,'% rev': np.sum,'movc_gbp': tmean ,'average order size': tmean }) .nlargest(10,'grossrevenue_gbp')   grp_data['country'] = 'eu'   key1 = grp_data.index.labels[0] key2 = grp_data['grossrevenue_gbp'].rank(ascending=false) sorter = np.lexsort((key2, key1))  grp_data = grp_data.take(sorter)   grp_data = grp_data[['% rev','grossrevenue_gbp', 'movc_gbp','average order size','ordercount','country']]

would appreciate help.

thanks,

i think need groupby first multiindex level , apply function nlargest:

grp_data = data.groupby(['new_category','cdi_cus_nm'])                 .aggregate({'grossrevenue_gbp':np.sum,                             'ordercount':np.sum,                            '% rev': np.sum,                            'movc_gbp': tmean ,                            'average order size': tmean })  df = grp_data.groupby('new_category')              .apply(lambda x: x.nlargest(1,'grossrevenue_gbp'))              .reset_index(level=0, drop=true)
