threads.append(thread4)#Wait for all threads to completefortinthreads: t.join()print"Exiting Main Thread"
Indicate that a formerly enqueued task is complete. Used by queue consumer threads. For each get() used to fetch a task, a subsequent call to task_done() tells the queue that the processing on the task is complete. If a join() is currently blocking, it will resume when all items have...

threads[-1].start() for thread in threads: """ Waits for threads to complete before moving on with the main script. """ thread.join() print(g) 最终输出的结果是3,通过Lock的使用,虽然在两个线程中修改了同一个全局变量,但两个线程是顺序计算出结果的。
start() # 等待所有线程完成 for thread in threads: thread.join() print("All threads completed") 在上述示例中,我们使用threading.Thread来创建多个线程,并将每个线程的目标函数设置为process_function。在循环结束后,我们启动每个线程,并使用join方法等待所有线程完成。 需要注意的是,由于GIL的存在,在多线程情况...
