Python默认继承？ [英] Python Default Inheritance?

问题描述

如果我在Python中定义一个类，例如：

If I define a class in Python such as:

class AClass:
   __slots__ = ['a', 'b', 'c']

它从哪个类继承？它似乎不继承自 object 。

Which class does it inherit from? It doesn't seem to inherit from object.

推荐答案

定义一个类，不声明任何特定的父类，该类将成为一个经典类，它的行为有点不同于继承自对象的新式类。有关详情，请参阅此处： http://docs.python.org/release/2.5.2/ ref / node33.html

If you define a class and don't declare any specific parent, the class becomes a "classic class", which behaves a bit differently than "new-style classes" inherited from object. See here for more details: http://docs.python.org/release/2.5.2/ref/node33.html

经典类没有公共根，所以实质上，您的AClass不会继承任何类。

Classic classes don't have a common root, so essentially, your AClass doesn't inherit from any class.

请注意，这是特定于3.0之前的Python版本。在Python 3中，所有类都是新式类，如果没有其他父类声明，则从对象隐式继承。

Note that this is specific to Python versions before 3.0. In Python 3, all classes are new-style classes and inherit implicitly from object, if no other parent is declared.
