python - Find uniqe combinations in DF

I need this code to go over a dictionary (many columns of a dataframe) and find the most unique combination values in the dimensions of a dataframe.

For example: in movies DF, if I send the columns genre and director + the measure Score to the function I'll get the max value from all unique combinations in genre and director:

def bi_robot(dataframe, dimensions, measure):
   t = {}
   for d in dimensions:
      du = dataframe[d].unique()
      t[d] = du[0]
   for v in t:
      key = v
      value = [t[v]]
      dataframe = dataframe.loc[dataframe[key].isin(value)] 
      stat = dataframe[measure].max()
   print('---------------------')
   print(t, end = '')  
   print(' Max:' + "{:.2f}".format(stat))
   print('---------------------')
   return t

df = df_rp.copy(deep = True)
filters = ['genre', 'director']
measure = 'score'
df = bi_robot(df, filters, measure)
