If you need async support in your program, you should try out AIOHTTP or HTTPX. The latter library is broadly compatible with Requests’ syntax. Because Requests is a third-party library, you need to install it before you can use it in your code. As a good practice, you should install ...
https://docs.python.org/3/library/asyncio.html 这边用一个简单的官方例子来说明async和await的执行顺序。 1 2 3 4 5 6 7 8 9 10 11 12 13 14 importasyncio asyncdefcompute(x, y): print("Compute %s + %s ..."%(x, y)) await asyncio.sleep(1.0) returnx+y asyncdefprint_sum(x, y):...
grequestsis a Python library that provides an elegant way to make asynchronous HTTP requests using the popularrequestslibrary. It builds on top of thegeventlibrary, which is a coroutine-based networking library. Withgrequests, you can send multiple HTTP requests in parallel, effectively leveraging the...

The Trio project aims to produce a production-quality, permissively licensed, async/await-native I/O library for Python. Like all async libraries, its main purpose is to help you write programs that do multiple things at the same time with parallelized I/O. A web spider that wants to ...
asyncio[2] “是一个使用 async/await 语法编写并发代码的库”,它在单个处理器上运行。 multiprocessing[3] “是一个支持使用 API 生产进程的包 [...] 允许程序员充分利用给定机器上的多个处理器”。每个进程将在不同的 CPU 中启动自己的 Python 解释器。
async def hello(request): return web.Response(text='Hello, world') app = web.Application() app.add_routes(routes) web.run_app(app) 1. 2. 3. 4. 5. 6. 7. 8. 把这段代码运行后,发现结果一模一样! 也就是说,喜欢哪种,就那么写就好了。
