A typical use for calling a cooperative superclass method is: class C(B): def meth(self, arg): super(C, self).meth(arg) New in version 2.2. 从说明来看,可以把类B改写如代码段3: 代码段3: class A(object): # A must be new-style class ...

Typical use to call a cooperative superclass method: class C(B): def meth(self, arg): super(C, self).meth(arg) 1. 2. 3. 4. 5. 6. 7. 由此可知, super有三种用法, 第一参数总是召唤父类的那个类, 第二参数可缺(返回非绑定父类对象),也可以是实例对象或该类的子类. 最终返回的都是父...
接下来程序在 SubClass类中定义了process()方法,该方法直接通过self调用name方法, Python将会执行子类重写之后的name方法。后面的代码通过显式调用 Base_Class 中的name方法,并显式为第1个参数self绑定参数值,这就实现了调用父类中被重写的方法。 5. 使用 super函数调用父类的构造方法...
**Python Super的用法** **一、基本用法** 1. In Python, `super()` is mainly used in class inheritance. It allows you to call methods from a superclass. For example, if you have a subclass that overrides a method from its superclass, you can still use the superclass method implementati...
super object; requires issubclass(type2, type) Typical use to call a cooperative superclass method: class C(B): def meth(self, arg): super().meth(arg) This works for class methods too: class C(B): @classmethod def cmeth(cls, arg): super().cmeth(arg) # (copied from class doc)...
