This version of server is not concurrent by design. When multiple clients try to connect to the server at about the same time, one client connects and occupies the server, while other clients wait until the current client disconnects. I wrote asimple simulation programto demonstrate this: $ ...
Python 3引入的asyncio模块进一步提升了网络编程的效率和代码可读性,通过协程(coroutine)和事件循环(event loop)机制,实现了高度并发的异步I/O。下面是一个使用asyncio创建TCP服务器的例子: import asyncio async def handle_client(reader, writer): data = await reader.read(100) message = data.decode() print(...
As a result, it returns a single future object, and, if you await asyncio.gather() and specify multiple tasks or coroutines, you’re waiting for all of them to be completed. (This somewhat parallels queue.join() from our earlier example.) The result of gather() will be a list of ...

Asynchronous HTTP Client/Server for asyncio and Python. Check out our full guide onhow to scrape with asyncio and aiohttp. aiohttpis package containing both a client and server framework, meaning it might be well suited for an API which also makes requests elsewhere. It has 11k stars on Githu...

当下,python都已经更新到了 Python3.12.X 了,如果你还没有使用过 asyncio、和 Python3.5 新增的 async/await 语法,那说明你可能真的是桃花源人,问今是何世,不知有汉,无论魏晋了。 在当下,基于 async/await 语法的异步 Web 框架也有很多,在 github 上找一找比比皆是是,那究竟应该选哪一款呢?在 github 上...
