How to find and show the position of an item in the list, not setting the string value for the search?

Question

How to find and show the position of an item in the list, not setting the string value for the search?

Ex:

nome_pessoa = str(input('Informe o seu nome completo: '))

lista_nomes = nome_pessoa.split()

After the names are divided and transformed into a list, I would like to know how, for example, to indicate the position the third name(or item) is.

Suppose that in this first execution, the user has entered the name : 'Pedro Lucas Gomes'.

That way, after transforming this string into the list with the names, it will have the items: ['Pedro', 'Lucas', 'Gomes'']

What I want in exit data, that is to say, printado on screen is:

The name of the second position, which in this case would be 'Gomes', and the position number, which will be 2.

BUT CASE AT SECOND RUN, the user type the name 'João Neves Frufru Feitosa', what I want on output is:

The name of the second position is 'Frufru', and the number of its position is 2.

Did you understand? I won’t use the command:

print(list_names.index('Frufru'))

Because the name 'Frufru' will not be fixed in the code! The name requested in the program, will be typed from the keyboard by the user at the time of each code execution.

(I thank everyone who is striving to help and I apologize for my lack of clarity before the issue)

Answer 1

Use "index" to pick the position of the item in the list.

lista_nomes.index('Gomes')

I don’t know if this is what you want, but this is the standard way to get an address on a list.

Answer 2

If you want to get the third item in the list, you should use brackets to access the item in the list you want. It’s important to remember that indexes start at 0, then to access the 3rd item, you must search for the index 2:

nome_completo = input('Por favor, informe seu nome completo: ')
lista_nome_completo = nome_completo.split()
print('O elemento 3 da lista é {}'.format(minha_lista[2]))

If you want to get the last name always, you should get the list size. A shortcut to the index is that -1 is the index of the last item.

nome_completo = input('Por favor, informe seu nome completo: ')
lista_nome_completo = nome_completo.split()
ultimo_elemento = len(lista_nome_completo) - 1
print('O último elemento da lista é o de número {}, e é {}'.format(ultimo_elemento, lista_nome_completo[-1]))
