从asyncpraw subreddit生成器对象中选择随机发布？

import asyncpraw
import random

# 配置你的 Reddit API 凭证
reddit = asyncpraw.Reddit(
    client_id='your_client_id',
    client_secret='your_client_secret',
    user_agent='your_user_agent'
)

async def get_random_post(subreddit_name):
    # 获取指定的 subreddit 对象
    subreddit = await reddit.subreddit(subreddit_name)
    
    # 获取该 subreddit 下的所有帖子
    submissions = []
    async for submission in subreddit.new(limit=None):  # limit=None 表示获取所有帖子
        submissions.append(submission)
    
    # 从帖子列表中随机选择一个
    if submissions:
        random_post = random.choice(submissions)
        return random_post
    else:
        return None

# 使用 asyncio 运行异步函数
import asyncio
random_post = asyncio.run(get_random_post('python'))
if random_post:
    print(f"随机选择的帖子标题: {random_post.title}")
else:
    print("没有找到帖子。")
