How to put uppercase and lowercase letters in the same variable without retyping them twice?

Question

I would need to use lowercase (a, e, i, o, u) and also uppercase (A, E, I, O, U) in self.all = variable.startswith(('a', 'e' , 'i', 'o', 'u')).

I SPECIFY that I don’t want two variables for Apple and for apple, but always use the same variable x (within which I will manually change Apple or apple).

I searched other questions on Stackoverflow, but there were only solutions with 2 variables/strings and that’s not what I’m looking for, so this question is not duplicate.

What I want is to print ok both when I write Apple in x and when i write apple in x. So I would like you to manually replace Apple with apple and try to print ok correctly.

x = "Apple"

class Vocal:
    def __init__(self, variable):
        self.all = variable.startswith(('a', 'e', 'i', 'o', 'u'))
        
vocal = Vocal(x)

if vocal.all:
    print(x, ": ok")
else:
    print(x, ": no")

Answer 1

You could convert the string to lowercase before checking.

variable.lower().startswith(('a', 'e', 'i', 'o', 'u'))

Alternatively, you could use a regular expression with the ignore case flag.

bool(re.match('(?i)[aeiou]', variable))

Answer 2

you can use the .upper() command or .lower() command to convert all characters in the string to upper or lowercase

class Vocal:
    def __init__(self, variable):
        self.Vocal = variable.lower().startswith(('a', 'e', 'i', 'o', 'u'))
