asyncio is used as a foundation for multiple Python asynchronous(异步) frameworks that provide high-performance network and web-servers, database connection libraries, distributed task queues, etc. asyncio模块有四个基本概念: eventloop coroutine
多线程适合于IO密集型任务(IO-bound tasks)。CPU密集型任务以CPU持续工作为特征,而IO密集型任务中有大量的等待时间,等待输入/输出的完成。 综上(to recap the above),并发包含了多进程(适用于CPU密集型任务)和多线程(IO密集型任务)。多进程是并行的一种形式,而并行又是并发的特殊形式/子类。Python标准库对这些...
It provides a virtual clock that advances the event loop time instantly upon any combination ofasyncio.sleep()calls in multiple coroutine tasks, by temporarily patching the event loop selector. This is also used inour timer test suite.
My personal recommendation is using the single threaded scheduler becuase you can combine a local set with the runtime giving you the ability to aquire the gil and still spawn futures because you have 'Send but this will change depending on what you need it for. Spawning rust tasks atleast ...
