import asyncio

from aio_pydispatch import Signal

server_start = Signal('server_start')
server_stop = Signal('server_stop')


def ppp(value: str) -> None:
    print(value)


async def main():
    server_start.connect(ppp)
    server_stop.connect(ppp)
    await server_start.send('server start')
    await asyncio.sleep(1)
    await server_stop.send('server stop')


if __name__ == '__main__':
    asyncio.run(main())
