python asyncio get_event_loop和new_event_loop的区别 python中的event,#线程之间用于交互的一个对象,这个event是一个内部的标签,线程可以等待这个标签的状态#举个例子,比如红绿灯是一个线程,三辆汽车是3个线程,如果为红灯,则三个汽车的线程必须#要停止,如果是绿灯

event_loop首先看一下selector中是否存在就绪的数据,存在的话就把对应的回调放到task list的尾部(如图),然后从头部继续run_task()。 你可能想问上面中断的task什么时候才能继续执行呢?我前一句说过了,event_loop每一次循环都会检测selector中是否存在就绪的i/o操作,如果存在就绪的i/o操作,我们对应就把callback放到...
