Discord.py meme命令需要很长时间

Question

我正在discord.py中制作一个机器人，并使用异步praw拥有一个完全工作的meme命令(praw没有工作)。但是这个模因的出现需要8到10秒的时间。有没有办法缩短时间？这是密码:-

@client.command(aliases=['memes'])
async def meme(ctx):
    subreddit = await reddit.subreddit("memes")
    all_subs = []
    top = subreddit.top(limit = 200)
    async for submission in top:
      
      all_subs.append(submission)
    
    random_sub = random.choice(all_subs)
    name = random_sub.title
    url = random_sub.url
    ups = random_sub.score
    link = random_sub.permalink
    comments = random_sub.num_comments
    embed = discord.Embed(title=name,url=f"https://reddit.com{link}", color=ctx.author.color)
    embed.set_image(url=url)
    embed.set_footer(text = f"{ups} {comments}")
    await ctx.send(embed=embed)

这需要一段时间，因为每次执行命令时，总是会生成一个要从中选择的提交列表，但是在命令执行后列表就会消失，这意味着每次执行命令都会生成200个posts，只需从一个命令中选择

如果你想要一个更高效，更快的方式，让它成为一个单独的功能！

all_subs = []


async def gen_memes():
    subreddit = await reddit.subreddit("memes")
    top = subreddit.top(limit = 200)
    async for submission in top:
      all_subs.append(submission)


@client.event
async def on_ready():
    await gen_memes()  # generate memes when bot starts

@client.command(aliases=['memes'])
async def meme(ctx):
    random_sub = random.choice(all_subs)
    all_subs.remove(random_sub)
    name = random_sub.title
    url = random_sub.url
    ups = random_sub.score
    link = random_sub.permalink
    comments = random_sub.num_comments
    embed = discord.Embed(title=name,url=f"https://reddit.com{link}", color=ctx.author.color)
    embed.set_image(url=url)
    embed.set_footer(text = f"{ups} {comments}")
    await ctx.send(embed=embed)
    
    if len(all_subs) <= 20:  # meme collection running out owo
        await gen_memes()

当然，这不是最有效的方法，如果你想在一定的时间间隔内填充你的模因，你可以使用discord.ext.tasks！
