为了解决这个问题,我们可以使用join()方法来等待其他线程或进程执行完毕。 importthreadingimporttimedeftask():time.sleep(5)print("Task completed")# Create a new threadt=threading.Thread(target=task)t.start()# Wait for the thread to finisht.join()print("All tasks completed") 1. 2. 3. 4. 5....

thread_letters = threading.Thread(target=print_letters) # Start the threads thread_numbers.start() thread_letters.start() # Wait for both threads to finish thread_numbers.join() thread_letters.join() 在这个示例中,print_numbers和print_letters可以在不同的线程中并发运行,从而提高了整体的执行速度。
# wait for the thread to finish t.join() 在这个示例中,我们创建了一个名为worker的函数,它将在一个新的线程中运行。我们使用threading.Thread类创建了一个新的线程对象,并将worker函数作为目标传递给它。然后,我们使用start()方法启动线程,并使用join()方法等待线程完成。
logging.info("Main : wait for the thread to finish") # x.join() logging.info("Main : all done") 查看日志语句,可以看到__main__部分正在创建并启动线程: 1 2 x = threading.Thread(target=thread_function, args=(1,)) x.start() 创建线程时,我们需要传递两个参数,第一个参数target是函数名...
16:16:30:Main:wait for the thread to finish 16:16:30:Main:all done >>> 16:16:32:Thread 1:finishing 这段运行结果中,注意到__main__程序已经运行完成,返回Main : all done,之后(守护)线程1才返回结果Thread 1: finishing。在返回Thread 1的结果之前停顿了两秒。这个停顿是Python在等待非守护线程(...

self._default_executor.shutdown(wait=True) AndThreadPoolExecutor.shutdown(wait=True)will wait for all of its threads to join. This is the code location which is "hanging". Setting the wait flag toFalsewill allow the loop to finish and exit, and theKeyboardInterruptwill be promptly shown to...
