classC(B): defmethod(self, arg): super(C,self).method(arg) 子类C重写了父类B中同名方法method,在重写的实现中通过super实例化的代理对象调用父类的同名方法。 super类的初始方法签名如下: 1 2 3 4 5 6 def__init__(self, type1, type2=None):# known special case of super.__init__ ...
参考文献:Python中的super用法详解_python_脚本之家 一、问题的发现与提出 在Python类的方法(method)中,要调用父类的某个方法,在Python 2.2以前,通常的写法如代码段1: 代码段1: classA:def__init__(self):print"enter A"print"leave A"classB(A):def__init__(self):print"enter B"A.__init__(self...
3.不要一说到 super 就想到父类!super 指的是 MRO(method resolution order) 中的下一个类! 另一篇比较好的文章:理解 Python super 1. python2 子类调用父类函数成员有2种方法:普通方法和super()方法 假设Base是基类 class Base(object): def __init__(self): ...
class SubClass(BaseClass): def method(self): super(SubClass, self).method() #do some thing here... 其中,最常见的method()是__init__() 以前做过Java,刚刚接触Python的继承,的确感觉有点奇怪,有时候还能搞混。。。当然这还是因为Java是单继承,只能用接口实现类似多继承的方式,而Python就直接支持多继承...
在上面的例子中,我们定义了一个ParentClass作为父类,它有一个my_method()方法。然后我们定义了一个ChildClass作为子类,它重写了my_method()方法,并在其中使用super().my_method()调用了父类的方法。当我们调用子类的my_method()方法时,它将首先输出父类的my_method()方法,然后输出子类的my_method()方法。二、...
