How can I store several letters in the same variable?

  • 772

I am trying to save the vowels in the variable "vowel" separating them by commas, but python takes it as a complete text.

letra = input(str("Introduzca una letra: "))
vocal = "a","e","i","o","u"

def abc(letra,vocal):
    if letra == vocal:
        print("True")
    else:
        print("False")    

abc(letra,vocal)

How can I get the variable to take the letters separately?

python

  1. the trick is to use the special "in" operator instead of the "==" comparison operator and to make the "vowel" variable a tuple (you can also do it with a str).

    letra = input(str("Introduzca una letra: "))
vocal = ("a","e","i","o","u")

def abc(letra,vocal):
    if letra in vocal:
        print("True")
    else:
        print("False")    

abc(letra,vocal)

    If you used your code when putting aeiou it would come out TRUE, but in AEIOU FALSE. Also in my code it would pass to TRUE, but to FALSE. This happens because it is case sensitive, it adds the vowels in capital letters to the tuple so that this does not happen.

    The code can be corrected and reduced:

    def abc(letra):
    return letra.lower() in "aeiou"

    The function reduces the letter to lowercase and then uses the "in" operator to check if the letter is part of the sequence "aeiou"

    A sequence can be a list, a tuple, and also a string.

    At the end, the function returns Trueor Falsedepending on whether the letter is a vowel or not.

    It is bad practice for functions to directly print the result; that prevents its use in other situations where you don't want to display the result.

    show

    You don't need to do either str("Introduzca una letra: "), since the text is already a string.

    def abc(letra):
    return letra.lower() in "aeiou"

letra = input("Introduzca una letra: ")
if abc(letra):
    print("Es vocal")
else:
    print("No es vocal")

    produces:

    Introduzca una letra: h
No es vocal

Process finished with exit code 0
