python 线程类 threading.Thread.run() 方法_python threading.thread.run()

    def run(self):
        """Method representing the thread's activity. 
        表示线程活动的方法。

        You may override this method in a subclass. The standard run() method
        invokes the callable object passed to the object's constructor as the
        target argument, if any, with sequential and keyword arguments taken
        from the args and kwargs arguments, respectively.

		您可以在子类中重写此方法。 
		标准的run（）方法调用传递给对象构造函数的可调用对象作为目标参数（如果有），
		并分别从args和kwargs参数中获取顺序参数和关键字参数。
