python类传参示例

class f():

    def __init__(self, *args, **kwargs):
        print('args Is', args)
　　　　　　 # args Is ('5', 'fff', 3, ' ')　　
        print('kwargs Is', kwargs)
　　　　　　 # kwargs Is {'kwargs': {'a': 1}}  6         print(type(kwargs))
        kwargs = kwargs.get('kwargs')
        # kwargs = kwargs['kwargs']
        self.a = kwargs.get('a')
        print('a is ', self.a)
        self.n = args[0]
        self.out = 1
        return super().__init__()

    def xx(self):
        for i in range(1, int(self.n)+1):
            self.out = self.out * i
        print(self.out)

20 # *args 为tuple类型入参，**kwagrs 为dict类型入参

x = f('5', 'fff', 3, ' ', kwargs={'a': 1}) 22 
22 x.xx()
