I want to return the largest and smallest string .
See:
nl=str(input('Digite uma string'))
String=[]
string.append(nl)
while caractere != 'pare':
caractere = str(input("Digite uma letra ou número "))
string.append(caractere)
Among the entries the user types, I would like to get the largest and smallest string and print them on the screen.
Just create a list, much like you already did:
textos = []
while True:
texto = input("Entre com um texto:")
if texto == 'pare':
break
textos.append(texto)
Then, to find the smallest and largest text, just use the native functions min and max , making use of the parameter key passing the function len . This way, you will get the smallest and largest text in relation to the return of the len function and not only the content of the text.
menor = min(textos, key=len)
maior = max(textos, key=len)
