如何让我的 meme 命令响应更快？在不和谐 py 重写

Question

是的，我见过this post，但这根本没有帮助。我想预加载模因或以一种方式缓存它们，或以任何其他方式减少等待时间。我曾尝试使用 asyncpraw，但由于某种原因，subreddit.top 在那里不起作用，所以我会坚持使用 praw。我的目标是减少等待时间，因为我必须等待超过 10 秒，如果我向 meme 命令发送垃圾邮件，机器人就会崩溃。所以我需要解决这个问题。

import discord 
from discord.ext import commands 
import praw
from bot_config.settings import botowner, avatarowner
from discord import Embed

    @commands.command(aliases=["memes", "r/memes", "reddit"])
    async def meme(self, ctx, subred="memes"):
        msg = await ctx.send('Loading ... <a:Loading:845258574434795570>')

        reddit = praw.Reddit(client_id='ID',
                             client_secret='SECRET',
                             username="USERNAME",
                             password='PASSWORD',
                             user_agent='AGENT')

        subreddit = reddit.subreddit(subred)
        all_subs = []
        top = subreddit.top(limit=350)

        for submission in top:
            all_subs.append(submission)

        random_sub = random.choice(all_subs)

        name = random_sub.title
        url = random_sub.url

        embed = Embed(title=f'__{name}__', colour=discord.Colour.random(), 
                      timestamp=ctx.message.created_at, url=url)

        embed.set_image(url=url)
        embed.set_author(name=ctx.author.display_name, icon_url=ctx.author.avatar_url)
        embed.set_footer(text=f'Bot by {botowner}', icon_url=avatarowner)
        await ctx.send(embed=embed)
        await msg.edit(content=f'<https://reddit.com/r/{subreddit}/>  :white_check_mark:')
        return

基本上，这使用了与您引用的帖子相同的想法，但我从您的代码中改编了它。

all_subs = []
oldSubred = "memes"
@commands.command(aliases=["memes", "r/memes", "reddit"])
async def meme(self, ctx, subred="memes"):
    global oldSubred
    if oldSubred != subred: # This checks if the subreddit from the previous time you used this command is the same as this time, if it's not, it picks brand new submissions, if it is, then the bot will use the submissions it got from the last time it ran the command, shortening the time needed to get a submission to send by a LOT
        all_subs.clear() # Clears all_subs if the desired subreddit is different from the posts inside all_subs

    msg = await ctx.send('Loading ... <a:Loading:845258574434795570>')

# You really shouldn't be logging into praw EVERY time you want to run this command, put this above the @commands.command
 #   reddit = praw.Reddit(client_id='ID',
 #                           client_secret='SECRET',
 #                           username="USERNAME",
 #                           password='PASSWORD',
 #                           user_agent='AGENT')

    subreddit = reddit.subreddit(subred)

    if all_subs == []: # Only gathers posts if all_subs is empty
        top = subreddit.top(limit=350)
        for submission in top:
            all_subs.append(submission)

    random_sub = all_subs[0] # Not really random anymore, just goes through the list
    all_subs.pop() # Gets rid of the 0 index variable from all_subs that we just used above

    name = random_sub.title
    url = random_sub.url

    embed = Embed(title=f'__{name}__', colour=discord.Colour.random(), 
                    timestamp=ctx.message.created_at, url=url)

    embed.set_image(url=url)
    embed.set_author(name=ctx.author.display_name, icon_url=ctx.author.avatar_url)
    embed.set_footer(text=f'Bot by {botowner}', icon_url=avatarowner)
    await ctx.send(embed=embed)
    await msg.edit(content=f'<https://reddit.com/r/{subreddit}/>  :white_check_mark:')
