asyncpraw | Async PRAW , an abbreviation for `` Asynchronous Python | REST library

The reason is praw and asyncpraw. As they are not made for getting posts, you shouldn't be using them. You can use RedditEasy which is 2x faster than praw in getting posts.

asyncpraw needs async and await in some places.

Documentation shows examples with async in for-loop

It takes a while because everytime you execute the command, it'll always generate a list of submissions to pick from but then the list just disappears after the command executes which means that you generate 200 posts every command execution just to pick from one

If you want a more efficient, faster way, make it a separate function!

asyncio.run explicity closes the loop on completion.

asyncio.run(coro, *, debug=False)

[...]
This function always creates a new event loop and closes it at the end.

This means the event loop is not available for cleanup once main finishes. Cleanup must instead be done deterministically, via async generators, or synchronously.

When managing the loop manually and not calling loop.close(), the loop remains available to schedule cleanup callbacks. Be aware that this does not necessarily mean cleanup is actually run unless the loop is explicitly resumed.

The problem in specific is a known issue with aiohttp 3.x.

In your meme command you are using a for loop to iterate the returned ListingGenerator, which is an async source. In this case you will need to use an async for loop to be able to iterate an async source.

Using a normal for loop you are not allowed to iterate over an async source unless you try blocking the event loop, because for calls __next__ as a blocking function and does not await its result.

There are some examples of how to iterate over the returned ListingGenerators in APRAW documentation.
