在Python3.6 你可以使用以下方法 import asyncio async def main(): pass loop = asyncio.get_event_loop() try: loop.run_until_complete(main()) finally: try: # 清理任何没有完全消耗的异步生成器。 loop.run_until_complete(loop.shutdown_asyncgens()) finally: loop.close() 如果代码可能运行在线程...
例子: importasyncioimportconcurrent.futuresdefblocking_io():# File operations (such as logging) can block the# event loop: run them in a thread pool.withopen('/dev/urandom','rb')asf:returnf.read(100)defcpu_bound():# CPU-bound operations will block the event loop:# in general it is p...
