Case insensitive prompt

[YUKI2eN3e]

Is there any way to make the prompt case insensitive while providing choices?
I have some code like this:

mode = Prompt.ask("What game mode do you wish to play", choices=["Long","Short"], default="Short").upper()
if mode == "L":
    mode = "LONG"
elif mode == "S":
    mode = "SHORT"

It shouldn't really matter how they type it in since as far as the rest of the code is concerned it might as well be a boolean

if mode == "LONG":
    #Stuff
if mode == "SHORT":
   #Other Stuff

so it would be nice to not have to prompt care about the capitalization.

This is very easy to create by subclassing Prompt. This transforms the input to lowercase, for example:

class LowercaseTransformingPrompt(Prompt):
    @classmethod
    def get_input(
        cls,
        console: Console,
        prompt: TextType,
        password: bool,
        stream: Optional[TextIO] = None,
    ) -> str:
        return (
            super()
            .get_input(console=console, prompt=prompt, password=password, stream=stream)
            .lower()
        )
