问题 I want to use both ThreadPoolExecutor from concurrent.futures and async functions. My program repeatedly submits a function with different input values to a thread pool. The final sequence of tasks that are executed in that larger function can be in any order, and I don't care about the return value, just that they execute at some point in the future. So I tried to do this async def startLoop(): while 1: for item in clients: arrayOfFutures.append(await config.threadPool.submit(threadWork, obj

问题 In trying to aggregate the results from an asynchronous generator, like so: async def result_tuple(): async def result_generator(): # some await things happening in here yield 1 yield 2 return tuple(num async for num in result_generator()) I get a TypeError: 'async_generator' object is not iterable when executing the async for line. But PEP 530 seems to suggest that it should be valid: Asynchronous Comprehensions We propose to allow using async for inside list, set and dict comprehensions.

问题 I'm trying to use the gaiohttp worker in Gunicorn with a Django app I'm developing with the following command: gunicorn -k gaiohttp -b localhost:8080 myproject.wsgi My ultimate goal is to be able to process requests concurrently - i.e. have 1 gunicorn worker process multiple requests concurrently. There are I/O bound operations which makes these requests slow. I know an event loop is already running when I'm processing a request: class MyView(View): def get(self, request): loop = asyncio.get

问题 I am trying to use the very new Django 3.1 Async view classes. Based on the limited documentation available, I have tried to create my own async def __call__() method. From the documents: For a class-based view, this means making its __call__() method an async def (not its __init__() or as_view() ). Django 3.1 Development Documents However, until now I have had no luck with writing an asynchronous class based view. I constantly get await exceptions, or asyncio.iscoroutinefunction returns

问题 A few days ago I became interested in programming discord bots a bit. In the syntax of these programs I noticed a lot of unintelligible issues that I can not find an answer to. That's why I am asking you for help in understanding them. All questions are based on this code: import discord import asyncio from discord.ext import commands botToken = '***' client = commands.Bot(command_prefix = '.') @client.event async def on_ready(): print('Bot is ready!') @client.event async def on_message

问题 I was wondering if there was any way to make this script a lot faster - like instantly create 1000 accounts for example or at least in a matter of a few seconds. I’ve tried doing some async stuff myself but this is as far as I could get, I am just a beginner with asynchronous programming so any help is appreciated. import asyncio import aiohttp async def make_numbers(numbers, _numbers): for i in range(numbers, _numbers): yield i async def make_account(): url = "https://example.com/sign_up.php
