asyncio 模块中的任务以协程对象作为参数创建,并且任务含有多种状态。 asyncio.create_task(coro, name=None) 此外,也可以使用 loop.create_task 或asyncio.ensure_future 创建协程任务 Task 实例。 loop.create_task(coro, name=None) ensure_future(coro_or_future, loop=None) 下面我们通过一个简单的例子来说明...

返回值是asyncio.Handle的一个实例,用于中止这个callback。 AbstractEventLoop.time() 返回当前时间,一个float值,根据事件循环的内部时钟。 1.4. Futures AbstractEventLoop.create_future() 创建一个关联到这个事件循环的asyncio.Future对象。
