I’m building a chatbot using the openai api library and thought it would be easier if I use the streamlit library to code some basic front end.
My code has its variables in Portuguese but I need some help to make my chat work.

That’s the code method:

# laço da conversa
    while True:
        user_message = st.chat_input(key=f"user_{i}")
        if user_message.lower() == "sair":
            print("conversa encerrada")
            break
        st.chat_message(f"Você: {user_message}")
        # cria as mensagens para enviar a API
        historico.append({"role": "user", "content": user_message})

        # gera resposta
        resposta = get_completion([msg['content'] for msg in historico])
        historico.append({"role": "assistant", "content": resposta})
        st.text(f"AI: {resposta}", key=f"assistant_{i}")
        i += 1


if __name__ == '__main__':
    main()

I just need the code to be like a chat bot but in a basic way.
