动态选择要继承的类 [英] Dynamically choosing class to inherit from

问题描述

我的Python知识有限，在以下情况下我需要一些帮助。

My Python knowledge is limited, I need some help on the following situation.

假设我有两个类， A 和 B ，是否有可能在Python中（概念上）执行以下操作：

Assume that I have two classes A and B, is it possible to do something like the following (conceptually) in Python:

import os
if os.name == 'nt':
    class newClass(A):
       # class body
else:
   class newClass(B):
       # class body

所以问题是我会想要创建一个类 newClass ，使其将基于平台差异从不同的基类继承，这可以在Python中做到吗？
谢谢。

So the problem is that I would like to create a class newClass such that it will inherit from different base classes based on platform difference, is this possible to do in Python? Thanks.

推荐答案

您可以使用条件表达式：

class newClass(A if os.name == 'nt' else B):
    ...
