Hi Alan and everybody Well, that is not exactly what I expected, but can help >>> lista = [] >>> for prod in itertools.product('aei', repeat=2): lista.append(prod) print(lista) [('a', 'a')] [('a', 'a'), ('a', 'e')] [('a', 'a'), ('a', 'e'), ('a', 'i')] [('a', 'a'), ('a', 'e'), ('a', 'i'), ('e', 'a')] [('a', 'a'), ('a', 'e'), ('a', 'i'), ('e', 'a'), ('e', 'e')] [('a', 'a'), ('a', 'e'), ('a', 'i'), ('e', 'a'), ('e', 'e'), ('e', 'i')] [('a', 'a'), ('a', 'e'), ('a', 'i'), ('e', 'a'), ('e', 'e'), ('e', 'i'), ('i', 'a')] [('a', 'a'), ('a', 'e'), ('a', 'i'), ('e', 'a'), ('e', 'e'), ('e', 'i'), ('i', 'a'), ('i', 'e')] [('a', 'a'), ('a', 'e'), ('a', 'i'), ('e', 'a'), ('e', 'e'), ('e', 'i'), ('i', 'a'), ('i', 'e'), ('i', 'i')] >>> Now I only need to put together in a single string all the elements that are grouped in parentheses, I think I can do that Thank you very much!
