使用 Python 定义函数时,貌似很少用到可变参数这种形式啊?

    看了一下,都是源码用的多,很少有自己写这种可变参数啊,大家平时用这种吗?

    def test_kwargs(first, *args, **kwargs):
       print 'Required argument: ', first
       for v in args:
          print 'Optional argument (*args): ', v
       for k, v in kwargs.items():
          print 'Optional argument %s (*kwargs): %s' % (k, v)
     
    test_kwargs(1, 2, 3, 4, k1=5, k2=6
