Python 列出父类的属性对象

我试图列出类的可设置属性

使用2个答案：和

这门课很有效

class A(object):
    def __init__(self):
        self._var_a = 1
        self._var_b = 2

    @property
    def var_a(self):
        return self._var_a
    @var_a.setter
    def var_a(self, value):
        self._var_a = value

    @property
    def var_b(self):
        return self._var_b

    @property
    def settable_property(self):
        settable_properties = {}
        for name, value in self.__class__.__dict__.iteritems():
            if isinstance(value, property) and value.fset is not None:
                settable_properties[name] = value
        return settable_properties

a = A()
a.settable_property 

我得到{'var_a'：属性{u对象}

但对于儿童班：

class B(A):
    def __init__(self):
        self._var_c = 1
        super(B, self).__init__()

    @property
    def var_c(self):
        return self._var_c
    @var_c.setter
    def var_c(self, value):
        self._var_c = value

b = B()
b.settable_property

我只得到{'var_c'：property_object}。我期望{'var\u c'：属性对象，'var\u a'：属性对象}

我知道这是因为self。类dict只返回该类的dict，而不是所有父类的dict

所以我的问题是，他们有没有一种方法来获得班级及其家长的口述的等价物

我试着使用dir（self），它确实给了我所有属性的名称，但并没有给我属性对象。并使用getattr（self，'property_name'）返回属性的.fget（）值，而不是属性对象

vars（B）也只返回{'var_B'：property object}

使用

使用dir和getattr的其他解决方案：

def settable_property(self):
    settable_properties = {}
    for name in dir(self.__class__:
        value = getattr(self.__class__, name)  # getattr on class not instance
        if isinstance(value, property) and value.fset is not None:
            # WARNING this property object is not bound to an instance
            # if you want to use it either pass the instance like:
            #     value.fget(self)
            # or bind the function to the instance: 
            #      value = value.fget.__get__(self, self.__class__)

            settable_properties[name] = value 
    return settable_properties

def settable_property(self):
    settable_properties = {}
    for name in dir(self.__class__:
        value = getattr(self.__class__, name)  # getattr on class not instance
        if isinstance(value, property) and value.fset is not None:
            # WARNING this property object is not bound to an instance
            # if you want to use it either pass the instance like:
            #     value.fget(self)
            # or bind the function to the instance: 
            #      value = value.fget.__get__(self, self.__class__)

            settable_properties[name] = value 
    return settable_properties
