import threading
​
# 继承Thread类创建线程
class MyThread(threading.Thread):
    def run(self):
        # 线程执行的代码
        print("Hello, World!")
​
        # 使用函数创建线程
def my_function():
    # 线程执行的代码
    print("Hello, World!")
​
    # 创建线程对象并启动线程
thread1 = MyThread()
thread2 = threading.Thread(target=my_function)
thread1.start()
thread2.start()
