如果函数在超时时间内执行完毕,run_with_timeout函数会返回函数的结果;如果函数在超时时间内没有执行完毕,它会抛出TimeoutException异常。 使用timeout函数的例子 下面是一个使用timeout函数的例子,我们将使用timeout函数来执行一个可能陷入无限循环的代码: definfinite_loop():whileTrue:passtry

threading.activeCount(): 返回正在运行的线程数量,与len(threading.enumerate())有相同的结果。 除了使用方法外,线程模块同样提供了Thread类来处理线程,Thread类提供了以下方法: run(): 用以表示线程活动的方法。 start():启动线程活动。 join([time]): 等待至线程中止。这阻塞调用线程直至线程的join() 方法被调用...
SystemExit Raised by the sys.exit() function. TypeError Raised when a function or operation is applied to an object of an incorrect type. UnboundLocalError Raised when a reference is made to a local variable in a function or method, but no value has been bound to that variable. UnicodeError...
后续就是启动线程,通过Thread.join(timeout)来设定等待的时间数。在等待之后,检查线程状态。如线程仍存活,说明超时。 thread = TerminableThread(target=run_func, daemon=True) thread.start() thread.join(timeout=sec) if thread.is_alive(): # a timeout thread keeps alive after join method, terminate ...
