Hi,  
I am just starting with gradio and copied a code from gradio

import gradio as gr  
import random  
import time  
from googletrans import Translator

translator = Translator()

def my \_translate\_func(response, translate\_to):  
return translator.translate(response,dest=translate\_to).text

#gradio chat1.py demo.app

with gr.Blocks() as demo:  
drop\_lang = gr.Dropdown([“nl”, “de”, “en”,“fr”], label=“Languages”)  
chatbot = gr.Chatbot()  
msg = gr.Textbox()  
clear = gr.Button(“Clear”)

```
def user(user_message, history):
    return "", history + [[user_message, None]]

def bot(message,history):
    bot_message = random.choice(["How are you?", "I love you", "I'm very hungry"])
    history[-1][1] = ""
    for character in bot_message:
        history[-1][1] += character
        time.sleep(0.05)
        yield history

msg.submit(user, [msg, chatbot], [msg, chatbot], queue=False).then(
    bot, chatbot, chatbot
)
clear.click(lambda: None, None, chatbot, queue=False)

```

demo.queue()  
demo.launch()

My question is how can i replace the example of random.choice(…)

with my my my \_translate\_func function. that it accepts the language chosen and the input from the textbox…

Thanks in advance.

Henry

I solve it by replacing the random with the translate function and as input the history[len(history)-1][0]

Hi @hboen!

Glad you figured it out. Yes the history is a list of lists. The first element of the list is the user message and the bot message is the second element. So you have the right idea!

I am trying to build a basicchatbot with streaming. from the documentation we have the following code. import gradio as gr import random import time with gr.Blocks() as demo: chatbot = gr.Chatbot() msg = gr.Textbox() clear = gr.Button("Clear") def respond(message, chat\_history): bot\_message = random.choice(["How are you?", "I love you", "I'm very hungry"]) chat\_history.append((message, bot\_message)) time.sleep(2) return "", chat\_h…

I am having a similar question to @hboen, but haven’t been able to figure how to make it work.

Any comment is greatly appreciated.
