import telegram
from telegram.ext import *
from telegram import Update
from telegram.ext import Updater, CommandHandler, MessageHandler, filters, CallbackContext

def start(update, context):
    update.message.reply_text("Как дела?")

def message_handler(update, context):
    text = update.message.text.lower()
    if "Хорошо" in text.split():
        update.message.reply_text("/next")
    elif "Плохо" in text.split():
        update.message.reply_text("Почему?")
    elif "собеседник завершил общение." in text:
        update.message.reply_text("/next")

def main():
    updater = Updater("TOKEN", update_queue=None)

    dispatcher = updater.dispatcher
    
    dispatcher.add_handler(CommandHandler("start", start))
    dispatcher.add_handler(MessageHandler(filters.text & ~filters.command, message_handler))

    updater.start_polling()
    updater.idle()

if __name__ == '__main__':
    main()
