获取实例的类名? [英] Getting the class name of an instance?
问题描述
如果我从中创建该对象的实例的基类是派生该实例的类的基类,那么如何找到在Python中创建对象实例的类的名称?
How do I find out a name of class that created an instance of an object in Python if the function I am doing this from is the base class of which the class of the instance has been derived?
正在考虑检查模块可能对我有所帮助,但似乎并没有给我我想要的东西.除了解析__class__
成员之外,我不确定如何获取此信息.
Was thinking maybe the inspect module might have helped me out here, but it doesn't seem to give me what I want. And short of parsing the __class__
member, I'm not sure how to get at this information.
推荐答案
您是否尝试过 __name__
属性?即type(x).__name__
将为您提供类的名称,我想这就是您想要的.
Have you tried the __name__
attribute of the class? ie type(x).__name__
will give you the name of the class, which I think is what you want.
>>> import itertools
>>> x = itertools.count(0)
>>> type(x).__name__
'count'
如果您仍在使用Python 2,请注意,上述方法适用于新式类仅(在Python 3+中,所有类都是新式"类).您的代码可能使用一些旧式类.两者均可使用:
If you're still using Python 2, note that the above method works with new-style classes only (in Python 3+ all classes are "new-style" classes). Your code might use some old-style classes. The following works for both:
x.__class__.__name__
