Question

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()

Answer 1

问题似乎在代码的这一点上

random_item = random.choice(random_answer)
.
.
.
if question_phrase in comment.body.lower():
     comment.reply(random_item)

您将在开始时将随机值分配给变量，并在以下功能中使用它。因此，它总是返回相同的值。

您可以通过这种方式进行更改并尝试。

if question_phrase in comment.body.lower():
    comment.reply(random.choice(random_answer))

Answer 2

启动程序时，您一次将随机选择分配给random_item。然后，您只是使用它来返回每个请求。要针对每个请求做出新的随机选择，请将随机选择移至该请求。

import praw
import random


random_answer = ['hello world 1', 'hello world 2', 'hello world 3']
QUESTIONS = ["!randomhelloworld"]

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():
          random_item = random.choice(random_answer)
          comment.reply (random_item)
        break


if __name__ == "__main__":
    main()
