如果无限循环在超时时间内没有执行完毕,run_with_timeout函数会抛出TimeoutException异常,并打印出"Code execution timed out"的提示信息。 总结 timeout函数是Python中一个非常有用的功能,可以帮助我们控制代码的执行时间,避免执行时间过长而导致程序卡住或消耗过多的资源。通过使用timeout函数,我们可以更好地管理代码...

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...
