在这个例子中，我们在原来的计时器装饰器上再加上一个print_args装饰器，用来打印函数的参数列表。在使用@语法糖将装饰器应用到countdown函数上时，Python会先应用最后一个装饰器，然后是倒数第二个，以此类推。因此，countdown函数实际上被先应用了print_args装饰器，然后是Timer装饰器。装饰器的应用场景 装饰器可以...

A simple graphical countdown timer based on theTimerclass. It can be used either as a python main program from a shell, or as a function in Python code or console. From a terminal: python -m oclock 1:45:00#start timer of duration 1 hour 45 minutespython -m oclock 1:45:#exactly ...
