async io

import asyncio
import threading


# 传入name参数:
async def hello(name):
    # 打印name和当前线程:
    print("Hello %s! (%s)" % (name, threading.current_thread))
    # 异步调用asyncio.sleep(1):
    await asyncio.sleep(10)
    print("Hello %s again! (%s)" % (name, threading.current_thread))
    return name

# syncio.ensure_future是Python asyncio库中用于安排协程或Future对象执行的函数，其核心作用是将可等待对象（如协程或Future）加入任务队列并确保其被调度执行，即使未被显式await

async def main():
    L = await asyncio.gather(hello("Bob"), hello("Alice"))
    #L = await asyncio.wait(hello("Bob"), hello("Alice"))
    print(L)

asyncio.run(main())
