How to add multiple lines response in chatterbot?

I am trying to build a simple chat bot using Pythons's chatterbot.
I am training this bot with the help of ListTrainer.
I have created a txt file containing questions-answers.
Problem I am facing with it is that if answers contains multiple lines, bot includes only first line in response.
Can you please help me to solve this issue?

from chatterbot.trainers import ListTrainer

from chatterbot import ChatBot

bot = ChatBot('MyBot')

conv = open('chats.txt','r').readlines()

bot.set_trainer(ListTrainer)

bot.train(conv)

while True:

   request = input('You:')

   response = bot.get_response(request)

 

print('Bot:',response)

And sample of chat.txt file is as below-
