如何使用python-telegram-bot删除群聊中超过2天的消息？

pip install python-telegram-bot

from telegram.ext import Updater

def delete_old_messages(update, context):
    chat_id = update.message.chat_id
    message_date = update.message.date
    two_days_ago = datetime.datetime.now() - datetime.timedelta(days=2)
    
    if message_date < two_days_ago:
        context.bot.delete_message(chat_id=chat_id, message_id=update.message.message_id)

def main():
    updater = Updater(token='YOUR_API_TOKEN', use_context=True)

    updater.dispatcher.add_handler(MessageHandler(Filters.text, delete_old_messages))

    updater.start_polling()
    updater.idle()

import datetime
from telegram.ext import Updater, MessageHandler, Filters

def delete_old_messages(update, context):
    chat_id = update.message.chat_id
    message_date = update.message.date
    two_days_ago = datetime.datetime.now() - datetime.timedelta(days=2)
    
    if message_date < two_days_ago:
        context.bot.delete_message(chat_id=chat_id, message_id=update.message.message_id)

def main():
    updater = Updater(token='YOUR_API_TOKEN', use_context=True)
    updater.dispatcher.add_handler(MessageHandler(Filters.text, delete_old_messages))
    updater.start_polling()
    updater.idle()

if __name__ == '__main__':
    main()
