Do I have to use lambda for rx.foreach?

[Dekubaka]

I'm going through the tutorial in the docs for the chat app and I see in rx.foreach, lambda is used here:

def chat() -> rx.Component:
    return rx.box(
        rx.foreach(
            State.chat_history,
            lambda messages: qa(messages[0], messages[1]),
        )
    )

If I didn't want to use lambda, how would I go about that?

First I thought I could do:

qa(State.chat_history[0], State.chat_history[1])

but that was dumb.

So I though I could just convert to a function because that's what lambda is:

def chat() -> rx.Component:
    return rx.box(
        rx.foreach(
            State.chat_history,
            test(State.chat_history),
        )
    )

def test(messages):
    return qa(messages[0], messages[1])

And then I realized idk wtf i'm doing here. For reference:

qa function

def qa(question: str, answer: str) -> rx.Component:
    return rx.box(

        rx.box(
            rx.text(question, style=style.question_style),
            text_align="right",
            ),

        rx.box(
            rx.text(answer, style=style.answer_style),
            text_align="left",
            ),

        margin_y="1em",
    )

State class for chat history list

class State(rx.State):
    # The current question being asked.
    question: str

    # Keep track of the chat history as a list of (question, answer) tuples.
    chat_history: list[tuple[str, str]]

    def answer(self):
        # Our chatbot is not very smart right now...
        answer = "I don't know!"
        self.chat_history.append((self.question, answer))
        self.question = ''

So I'm just curious at this point, how would I go about not using lambda, or is it necessary for this?

I asked the discord. I was close but the alternative was

def chat() -> rx.Component:
    return rx.box(
        rx.foreach(
            State.chat_history,
            test
        )
    )

def test(messages):
    return qa(messages[0], messages[1])
