这篇文章主要介绍了python super用法及原理详解,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下
概念
super作为python的内建函数。主要作用如下：
- 允许我们避免使用基类
- 跟随多重继承来使用
实例
在单个继承的场景下，一般使用super来调用基类来实现：

class Mammal(object): def __init__(self, mammalName): print(mammalName, 'is a warm-blooded animal.') class Dog(Mammal): def __init__(self): print('Dog has four legs.') super().__init__('Dog') d1 = Dog() |
输出结果：
➜ super git:(master) ✗ py super_script.py
Dog has four legs.
Dog is a warm-blooded animal.
