简单的说super().init(),就是继承父类的init方法,同样可以使用super()去继承其他方法。 super不是关键字,而是一个类, 调用super()会创建一个super对象: 实例 单继承 class Father: def __init__(self,name='Tom'): self.name=name class Son1(Father): pass class Son2(Father): def __init__(self...
class Manager(Employee, Customer): def __init__(self, salary, favorite, address): super().__init__(salary) # super(Manager, self).__init__(salary) 作用同上, # super调用父类的方法,由于继承了两个类,super根据mro顺序来确定调用哪个父类,子类继承写在前面的类 # 使用未绑定的方式调用Customer...
def __init__(self, name): self.name = name print("create an instance of:", self.__class__.__name__) print("name attribute is:", self.name) class Child(Parent): def __init__(self): print("call __init__ from Child class") super(Child,self).__init__("data from Child")...
zone = zone super().__init__(name, mode, number) # 继承super class __init__属性 def desc(self): print( f'This is {self.name}_{self.mode}_{self.number} switch. made in {self.zone}') print(f'New feature: {self.l3protocol}') if __name__ == '__main__': ...
super()函数的用法如下: classSubClass(ParentClass):def__init__(self,*args,**kwargs):super().__init__(*args,**kwargs) 1. 2. 3. 在上面的代码中,SubClass是子类,ParentClass是父类。在子类的构造函数中,通过调用super().__init__(*args, **kwargs)来调用父类的构造函数。
classB(A):def __init__(self):print "B:__init__"A.__init__(self) #使用类名直接调用 super(B, self).__init__() #使用super关键字调用 deffun(self):print "B:fun"A.fun(self) super(B, self).fun()print 1. 2. 3. 4.
