Reddit Bot：随机回复评论

此reddit机器人旨在在调用关键字'！randomhelloworld'时对子 reddit中的评论使用随机答案进行回复。它会答复，但始终显示相同的注释，除非我停止并重新运行该项目。如何调整代码，使其始终显示随机注释？

import praw

import random





random_answer = ['hello world 1', 'hello world 2', 'hello world 3']

QUESTIONS = ["!randomhelloworld"]

random_item = random.choice(random_answer)



def main():

    reddit = praw.Reddit(

        user_agent="johndoe",

        client_id="johndoe",

        client_secret="johndoe",

        username="johndoe",

        password="johndoe",

    )



    subreddit = reddit.subreddit("sandboxtest")

    for comment in subreddit.stream.comments():

            process_comment(comment)





def process_comment(comment):

    for question_phrase in QUESTIONS:

        if question_phrase in comment.body.lower():

         comment.reply (random_item)

        break





if __name__ == "__main__":

    main()
