@nosklo的基于扭曲的解决方案既优雅又可行，但是如果您希望避免对Twisted的依赖，则该任务仍然可行，例如：
import multiprocessingdef query_with_timeout(dbc, timeout, query, *a, **k): conn1, conn2 = multiprocessing.Pipe(False) subproc = multiprocessing.Process(target=do_query, args=(dbc, query, conn2)+a, kwargs=k) subproc.start() subproc.join(timeout) if conn1.poll(): return conn1.recv() subproc.terminate() raise TimeoutError("Query %r ran for >%r" % (query, timeout))def do_query(dbc, query, conn, *a, **k): cu = dbc.cursor() cu.execute(query, *a, **k) return cu.fetchall()
