创建定时器:首先导入threading和time模块,然后定义一个函数task,用来执行定时器任务。创建定时器对象timer,通过Timer类指定定时时间和任务函数,args参数用来传递任务函数所需的参数。 importthreadingimporttimedeftask(param):print("This is a task with parameter:",param)timer=threading.Timer(5,task,args=("example...

One example of a reason to subclass Thread is provided by Timer, also included in threading. A Timer starts its work after a delay, and can be canceled at any point within that delay time period. Thread的一个重要继承类是Timer,它也在threading目录下。一个Timer对象在一个delay后开始工作,并且...
Shell $ python timer.py 5 However, with run() you need to pass the command as a sequence, as shown in the run() example. Each item in the sequence represents a token which is used for a system call to start a new process.
