Why does the asyncio's event loop suppress the KeyboardInterrupt on Windows?
There is workaround for Windows. Run another corouting which wake up loop every second and allow loop to react on keyboard interrupt
Example with Echo server from asyncio doc
async def wakeup(): while True: await asyncio.sleep(1)loop = asyncio.get_event_loop()coro = loop.create_server(EchoServerClientProtocol, '127.0.0.1', 8888)server = loop.run_until_complete(coro)# add wakeup HACKloop.create_task(wakeup())try: loop.run_forever()except KeyboardInterrupt: pass
If you just want to exit the program and don't need to catch the KeyboardInterrupt, the signal module provides a simpler (and more efficient) workaround:
# This restores the default Ctrl+C signal handler, which just kills the processimport signalsignal.signal(signal.SIGINT, signal.SIG_DFL)# Now the event loop is interruptableimport asyncioasyncio.get_event_loop().run_forever()
