python异步---trio

用法

pip install trio

语法上与curio类似，与asyncio更轻量级

import trio


async def child1():
    print("child1")
    await  trio.sleep(1)
    print("child1 exist")


async def child2():
    print("child2")
    await trio.sleep(1)
    print("child2 exist")


async def parent():
    print("parent")
    async with trio.open_nursery() as nursery:
        print("spawing child1")
        nursery.start_soon(child1)
        print("spawing child2")
        nursery.start_soon(child2)

trio.run(parent)
