我该如何从其他异步函数调用的同步函数调用异步代码？

Question

我需要从其他异步函数调用的同步代码中调用异步代码

我尝试做Setting a descriptor in python3.5 asynchronously，但是这个答案对我没有帮助

async def first():
    return second()


def second():
    # TODO: In this function I want to call function thrird,
    #       and I want to call it asynchronous!
    #       This function MUST be syncronious (for example __get__)


async def third():
    await asyncio.sleep(1)


async def main():
    await asyncio.gather(
        first(),
        first()
    )
    # must work 1 second


asyncio.run(main())

此代码必须工作1秒，而不是2秒
