是否可以覆盖从对象派生的"__name__"? [英] Is it possible to override `__name__` derived from object?

问题描述

要获取类名的字符串表示形式，我们可以使用obj.__class__.__name__，是否可以重载这些方法，以便我可以返回字符串而不是实际的类名?

To get a string representation of a class name we can use obj.__class__.__name__ is it possible to overload these methods so that I can return my string instead of the actual class name?

推荐答案

让我们尝试！ (是的，这可行):

Let's try! (Yes, this works):

>>> class Foo(object):
...     pass
...
>>> obj = Foo()
>>> obj.__class__.__name__ = 'Bar'
>>> obj
<__main__.Bar object at 0x7fae8ba3af90>
>>> obj.__class__
<class '__main__.Bar'>

您也可以刚刚完成Foo.__name__ = 'Bar'，我使用obj.__class__.__name__来与您的问题保持一致.

You could also have just done Foo.__name__ = 'Bar', I used obj.__class__.__name__ to be consistent with your question.
