python 使用 asyncio 执行并发任务

import asyncio


async def factorial(name, number):
    print(f"开始执行 {name}")
    print(f"Task {name}: factorial({number})")
    await  asyncio.sleep(3)
    print(f"任务执行结束{name}")
    return number


async def main():
    task = []
    name_list = [("A", 2), ("B", 3), ("C", 4)]
    for name in name_list:
        task.append(factorial(name[0], name[1]))

    L = await asyncio.gather(
        *task
    )
    print(L)


asyncio.run(main())
