1. 创建线程：使用 threading.Thread 类实例化一个线程，可以传入一个函数作为 target。import threadingdefrun(): print("Running thread")# 创建线程thread = threading.Thread(target=run)2. 启动线程：使用线程的 start() 方法启动线程。thread.start()3. 等待线程结束：使用线程的 join() 方法等待线程结束。

Thread(target=long_running_task) thread.start() 在需要停止线程的地方,设置一个标志位来通知线程停止运行。例如: 代码语言:python 代码运行次数:0 复制Cloud Studio 代码运行 import threading # 标志位,用于通知线程停止运行 stop_flag = False def long_running_task(): while not stop_flag: # 长时间运行...
