using the "RANDOM" library mix a pre-existing list organizing the elements in coupes so that the programs gives each element another element different than itself.

import random as rd
lista_studenti = ["Fabio", "Rita", "Francesca", "Paolo", "Luca", "Giacomo", "Ilaria", "Giovanni", "Elena", "Angelo"]

def partner(x):
  n = len(x)
  rd.shuffle(x)
  for i in range(0, n, 2):
    print(x[i], "--", x[i+1])
    
partner(lista_studenti)
