How to stop listener in telegram bot?

Question

Python

I have such a problem. I created a handler, in which I put bot.set_update_listener(listener), inside which, under a certain condition, the listener stops. The condition is met, but the listener does not stop and continues. But why? how can i fix this problem? it turns out because the listener is in one handler, then I can't use another one, so I would have to close it

def listener(messages):
        for m in messages:
                chatid = m.chat.id
                print(m.content_type)
                print('this is text')
                text = m.text
                if m.text =='/close':
                    break
                bot.send_message(chatid, text)


bot.set_update_listener(listener)
