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：
下面是一个例子：
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.
super在多重继承里面的使用：
下面是一个例子：
class Animal:
def __init__(self, animalName):
print(animalName, 'is an animal.');
class Mammal(Animal):
def __init__(self, mammalName):
print(mammalName, 'is a warm-blooded animal.')
super().__init__(mammalName)
class NonWingedMammal(Mammal):
def __init__(self, NonWingedMammalName):
print(NonWingedMammalName, "can't fly.")
super().__init__(NonWingedMammalName)
class NonMarineMammal(Mammal):
def __init__(self, NonMarineMammalName):
print(NonMarineMammalName, "can't swim.")
super().__init__(NonMarineMammalName)
class Dog(NonMarineMammal, NonWingedMammal):
def __init__(self):
print('Dog has 4 legs.');
super().__init__('Dog')
d = Dog()
print('')
bat = NonMarineMammal('Bat')
输出结果：
➜ super git:(master) ✗ py super_muli.py Dog has 4 legs. Dog can't swim. Dog can't fly. Dog is a warm-blooded animal. Dog is an animal. Bat can't swim. Bat is a warm-blooded animal. Bat is an animal.
