在 Win10 中使用 CTRL+C 无法从 python 脚本退出

Question

With the following code I'm unable to quit using CTRL+C after running it. I also tried to catch KeyboardInterrupt from different code positions without success. I'm using Windows 10 x64 and Python 3.7.6.

async def handle_req(self, reader: StreamReader, writer: StreamWriter):
    try:
        data = await reader.read()
        msg = data.decode()

        addr = writer.get_extra_info('peername')

        print(f"Received {msg!r} from {addr!r}")

        writer.write("Res".encode())
        writer.write_eof()
        await writer.drain()

        writer.close()
    except OSError:
        print("Client endpoint unreachable")


async def main():

    try:

        server = await asyncio.start_server(handle_req, "127.0.0.1", 9000)
        addr = server.sockets[0].getsockname()
        print(f'Serving on {addr}')

        async with server:
            await server.serve_forever()

    except KeyboardInterrupt:
        server.close()
        server.wait_closed()
        raise


if __name__ == '__main__':
    try:
        loop = asyncio.get_event_loop()
        loop.run_until_complete(main())
    except KeyboardInterrupt:
        loop.stop()
        loop.close()

your using exception for the keyboard interruptions so try import sys and following lines

import sys

if __name__ == '__main__':
try:
    loop = asyncio.get_event_loop()
    loop.run_until_complete(main())
except KeyboardInterrupt:
    loop.stop()
    loop.close()
    sys.exit()
