For now, just know that an awaitable object is either (1) another coroutine or (2) an object defining an .__await__() dunder method that returns an iterator. If you’re writing a program, for the large majority of purposes, you should only need to worry about case #1. That brings...
This is really nice and straightforward, but the point is that this process will spend a tonne of time sleeping while the send() method completes transferring all of the data. 这个示例简洁而直观,但是在执行send()方法完成所有数据传输时,会消耗很多的时间用在等待中。 Non-Blocking I/O 非阻塞模式...

equivalents in Python 3.5/3.6 - for example, there's async with for asynchronous context managers, and async for for asynchronous iterators - but they require the objects you're using them on to have provided asynchronous implementations of those operations (like defining an __aiter__ method)....
python的multiprocessing library是有三种start method的,其中最常用的两种是fork和spawn。前者现在主要是Linux用,后者是MacOS和Windows的默认方式(MacOS支持fork,但是3.8之后不推荐)。之前的多进程trace只能支持fork,也就是Unix体系,现在spawn也能用了,做到了全平台覆盖~...
