Excuse me for the basic question. It's just that I do not understand when we have to use + in Input . Here is an example of a command below. Why does not my code work when I put str(i) between commas?
i = 1
textos = []
texto = input("Digite o texto " + str(i) +" (aperte enter para sair):")
Your code does not work with commas because, by commas, you are implicitly creating a tuple (a data structure). In your case, the input function receives one string per parameter, not a tuple. If in doubt, always use the + sign for concatenation, or a function called format . Here's an example:
mensagem = 'Digite o texto {} (aperte enter para sair):'.format(i)
texto = input(mensagem)
where {} will be replaced by the value passed by parameter in the format method (in this case the variable i ).
You can use the formatting operator % , for example:
i = 1
textos = []
texto = input("Digite o texto %d (aperte enter para sair):" % (i) )
Or you can use the format() method , for example :
i = 1
textos = []
texto = input("Digite o texto {} (aperte enter para sair):".format(i))
