MRO is a mechanism to resolve the method to be executed when super notation is used. A common confusion occurs in case of multiple inheritance. What if a common method is implemented in multiple parents and it is called using super(), from which class should the method be called? This is...
MRO(method resolution order) Python 支持多继承,如果父类中有相同名字的方法,在子类中没有指定父类名字的时候,解释器将根据 从左到右 按顺序搜索。 我们可以通过 类.mro() 来获得类的层次结构图 ,方法 的解析顺序也是按照这个来的。 classA:defaa(self):print("aa")defsay(self):print("aa")classB:def...
在Python中,类的属性 __mro__可以获取类的继承顺序,它返回一个tuple,Python按照此顺序,一级一级进行查找,保证父类的函数只调用一次 super(),是从第一个参数类的上一级开始查找 在Python3中,可省略super的参数,省略时默认为调用当前类的父类class A(object): def __init__(self): print("class --- A ...
A metaclass is the class of a class. Like a class defines how an instance of the class behaves, a metaclass defines how a class behaves. A class is an instance of a metaclass. While in Python you can use arbitrary callables for metaclasses (like Jerub shows), the more useful approach...
