asyncio异步IO--协程(Coroutine)与任务(Task)详解 协程 协程(coroutines)是通过async/await定义函数或方法,是使用asyncio进行异步编程的首选途径。如下,是一个协程的例子: 1 2 3 4 5 6 import asyncio asyncdefmain(): print("hello") await asyncio.sleep(1)...
Wait for that sender task to finish… …then remove the entry in the SEND_QUEUES collection (and in the next line, we also remove the sock from the SUBSCRIBERS collection as before). The send_client() coroutine function is very nearly a textbook example of pulling work off a queue. Note...
