在 Python 对象中，如何查看已使用 @property 装饰器定义的属性列表? [英] In a Python object, how can I see a list of properties that have been defined with the @property decorator?

问题描述

我可以使用 self.__dict__ 查看一流的成员变量，但我还想查看使用 @property 装饰器.我该怎么做?

I can see first-class member variables using self.__dict__, but I'd like also to see a dictionary of properties, as defined with the @property decorator. How can I do this?

推荐答案

您可以向类中添加如下所示的函数:

You could add a function to your class that looks something like this:

def properties(self):
    class_items = self.__class__.__dict__.iteritems()
    return dict((k, getattr(self, k)) 
                for k, v in class_items 
                if isinstance(v, property))

这会查找类中的所有属性，然后为每个属性创建一个字典，其中包含当前实例值的每个属性.

This looks for any properties in the class and then creates a dictionary with an entry for each property with the current instance's value.
