python 類 __call__

標籤：self   bsp   nbsp   int   __init__   class   object   code   括弧   

 

__call__ 對象後面加括弧，觸發執行。

即：對象() 或者 類()()

 

class dog(object):    def __init__(self,name):        self.name = name    def eat(self):        print("%s is eating %s" % (self.name,‘ss‘))    def talk(self):        print("%s is taking" % self.name)    def __call__(self, *args, **kwargs):        print("you are ok？", args, kwargs)d = dog("jianlin")d()d(1,2,3,name="mike")‘‘‘you are ok？ () {}you are ok？ (1, 2, 3) {‘name‘: ‘mike‘}‘‘‘

另外一種實現

class dog(object):    def __init__(self,name):        self.name = name    def eat(self):        print("%s is eating %s" % (self.name,‘ss‘))    def talk(self):        print("%s is taking" % self.name)    def __call__(self, *args, **kwargs):        print("you are ok？", args, kwargs)dog("jianlin")()# you are ok？ () {}
