这似乎是可行的(但见下文):

class data(dict,object):
    def __init__(self,*args,**argd):
        dict.__init__(self,*args,**argd)
        self.__dict__.update(self)
    def __setattr__(self,name,value):
        raise AttributeError,"Attribute '%s' of '%s' object cannot be set"%(name,self.__class__.__name__)
    def __delattr__(self,name):
        raise AttributeError,"Attribute '%s' of '%s' object cannot be deleted"%(name,self.__class__.__name__)

如果您需要更复杂的行为，请随意编辑您的答案。

对于大型数据集，以下方法可能更节省内存:

class data(dict,object):
    def __init__(self,*args,**argd):
        dict.__init__(self,*args,**argd)
    def __getattr__(self,name):
        return self[name]
    def __setattr__(self,name,value):
        raise AttributeError,"Attribute '%s' of '%s' object cannot be set"%(name,self.__class__.__name__)
    def __delattr__(self,name):
        raise AttributeError,"Attribute '%s' of '%s' object cannot be deleted"%(name,self.__class__.__name__)

对我有用的是:

class C:
    def __init__(self):
        self._x=None

    def g(self):
        return self._x

    def s(self, x):
        self._x = x

    def d(self):
        del self._x

    def s2(self,x):
        self._x=x+x

    x=property(g,s,d)


c = C()
c.x="a"
print(c.x)

C.x=property(C.g, C.s2)
C.x=C.x.deleter(C.d)
c2 = C()
c2.x="a"
print(c2.x)

---

输出

a
aa

如果需求是基于某些实例属性动态生成属性，那么下面的代码可能会有用:

import random  

class Foo:
    def __init__(self, prop_names: List[str], should_property_be_zero: bool = False) -> None:
        self.prop_names = prop_names
        self.should_property_be_zero = should_property_be_zero
        
    def create_properties(self):
        for name in self.prop_names:
            setattr(self.__class__, name, property(fget=lambda self: 0 if self.should_property_be_zero else random.randint(1, 100)))

需要注意的重要一点是使用setattr(self。__class__进行名称,…),而不是setattr(自我、名称…)

使用的例子:

In [261]: prop_names = ['a', 'b']

In [262]: ff = Foo(prop_names=prop_names, should_property_be_zero=False)

In [263]: ff.create_properties()

In [264]: ff.a
Out[264]: 10

In [265]: ff.b
Out[265]: 37

In [266]: ft = Foo(prop_names=prop_names, should_property_be_zero=True)

In [267]: ft.create_properties()

In [268]: ft.a
Out[268]: 0

In [269]: ft.b
Out[269]: 0

设置属性将引发AttributeError:不能按预期设置属性:

In [270]: ff.a = 5
---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
<ipython-input-270-5f9cad5b617d> in <module>
----> 1 ff.a = 5

AttributeError: can't set attribute

In [271]: ft.a = 5
---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
<ipython-input-271-65e7b8e25b67> in <module>
----> 1 ft.a = 5

AttributeError: can't set attribute

你可以使用下面的代码来使用字典对象更新类属性:

class ExampleClass():
    def __init__(self, argv):
        for key, val in argv.items():
            self.__dict__[key] = val

if __name__ == '__main__':
    argv = {'intro': 'Hello World!'}
    instance = ExampleClass(argv)
    print instance.intro

我想我应该扩展这个答案，现在我长大了，更聪明了，知道发生了什么。迟到总比不到好。

可以动态地向类添加属性。但这就是问题所在:你必须把它添加到类中。

>>> class Foo(object):
...     pass
... 
>>> foo = Foo()
>>> foo.a = 3
>>> Foo.b = property(lambda self: self.a + 1)
>>> foo.b
4

属性实际上是描述符的简单实现。它是一个对象，为给定类的给定属性提供自定义处理。有点像从__getattribute__中分解出一个巨大的if树。

When I ask for foo.b in the example above, Python sees that the b defined on the class implements the descriptor protocol—which just means it's an object with a __get__, __set__, or __delete__ method. The descriptor claims responsibility for handling that attribute, so Python calls Foo.b.__get__(foo, Foo), and the return value is passed back to you as the value of the attribute. In the case of property, each of these methods just calls the fget, fset, or fdel you passed to the property constructor.

描述符实际上是Python暴露其整个OO实现管道的方式。事实上，还有一种比属性更常见的描述符。

>>> class Foo(object):
...     def bar(self):
...         pass
... 
>>> Foo().bar
<bound method Foo.bar of <__main__.Foo object at 0x7f2a439d5dd0>>
>>> Foo().bar.__get__
<method-wrapper '__get__' of instancemethod object at 0x7f2a43a8a5a0>

简单的方法只是另一种描述符。它的__get__将调用实例作为第一个参数;实际上，它是这样做的:

def __get__(self, instance, owner):
    return functools.partial(self.function, instance)

不管怎样，我怀疑这就是为什么描述符只在类上起作用:它们是首先为类提供动力的东西的形式化。它们甚至是规则的例外:您可以明显地为类分配描述符，而类本身就是类型的实例!事实上，我试着读Foo。Bar仍然调用property.__get__;描述符在作为类属性访问时返回自己，这只是一种习惯。

我认为几乎所有Python的OO系统都可以用Python来表达，这非常酷。：）

哦，如果你感兴趣的话，我之前写过一篇关于描述符的冗长博文。

很多提供的答案需要这么多行每个属性，即/和/或-我认为一个丑陋或乏味的实现，因为多个属性需要重复，等等。我更喜欢把事情简化，直到它们不能再简化，或者直到这样做没有多大意义为止。

简而言之:在完成的作品中，如果我重复2行代码，我通常会将其转换为单行helper函数，等等……我简化了数学或奇怪的参数，如(start_x, start_y, end_x, end_y)到(x, y, w, h)即x, y, x + w, y + h(有时需要min / max或如果w / h为负，实现不喜欢它，我将从x / y和abs w / h等中减去。)．

重写内部getter / setters是一个不错的方法，但问题是你需要对每个类都这样做，或者将类父化到那个基…这对我来说并不适用，因为我更喜欢自由地选择继承的子/父节点，子节点等。

我已经创建了一个解决方案，回答了这个问题，而不使用Dict数据类型来提供数据，因为我发现输入数据很乏味，等等…

我的解决方案需要你在你的类上面添加2行额外的代码，为你想要添加属性的类创建一个基类，然后每一行，你可以选择添加回调来控制数据，当数据发生变化时通知你，限制可以基于值和/或数据类型设置的数据，等等。

您还可以选择使用_object。x, _object。X = value， _object。GetX()， _object。SetX(value)，它们被等效地处理。

Additionally, the values are the only non-static data which are assigned to the class instance, but the actual property is assigned to the class meaning the things you don't want to repeat, don't need to be repeated... You can assign a default value so the getter doesn't need it each time, although there is an option to override the default default value, and there is another option so the getter returns the raw stored value by overriding default returns ( note: this method means the raw value is only assigned when a value is assigned, otherwise it is None - when the value is Reset, then it assigns None, etc.. )

There are many helper functions too - the first property which gets added adds 2 or so helpers to the class for referencing the instance values... They are ResetAccessors( _key, .. ) varargs repeated ( all can be repeated using the first named args ) and SetAccessors( _key, _value ) with the option of more being added to the main class to aide in efficiency - the ones planned are: a way to group accessors together, so if you tend to reset a few at a time, every time, you can assign them to a group and reset the group instead of repeating the named keys each time, and more.

实例/原始存储值存储在类中。， __类。引用访问器类，该类保存属性的静态变量/值/函数。_class。属性本身，在设置/获取等过程中通过实例类访问时被调用。

Accessor _class。__指向类，但因为它是内部的，所以需要在类中赋值，这就是为什么我选择使用__Name = AccessorFunc(…)要为它赋值，每个属性一行，并使用许多可选参数(使用键控可变参数，因为它们更容易识别和维护)…

I also create a lot of functions, as mentioned, some of which use accessor function information so it doesn't need to be called ( as it is a bit inconvenient at the moment - right now you need to use _class..FunctionName( _class_instance, args ) - I got around using the stack / trace to grab the instance reference to grab the value by adding the functions which either run this bit marathon, or by adding the accessors to the object and using self ( named this to point out they're for the instance and to retain access to self, the AccessorFunc class reference, and other information from within the function definitions ).

它还没有完全完成，但它是一个很好的立足点。注意:如果你不使用__Name = AccessorFunc(…)要创建属性，你将无法访问__键，即使我在init函数中定义了它。如果你这样做了，那么就没有问题。

另外:注意Name和Key是不同的…名称为“正式”，用于函数名称创建，键用于数据存储和访问。ie _class。其中小写x是键，名称将是大写x，因此GetX()是函数而不是GetX()，这看起来有点奇怪。这允许self。x工作和看起来合适，但也允许GetX()和看起来合适。

我有一个例子类设置键/名称相同，不同的显示。为了输出数据而创建了许多helper函数(注意:不是所有这些都是完整的)，所以你可以看到正在发生什么。

使用键:x，名称:x的当前函数列表输出如下:

这绝不是一个全面的列表-有一些在发布时还没有在这个列表上…

_instance.SetAccessors( _key, _value [ , _key, _value ] .. )                   Instance Class Helper Function: Allows assigning many keys / values on a single line - useful for initial setup, or to minimize lines.    In short: Calls this.Set<Name>( _value ) for each _key / _value pairing.
_instance.ResetAccessors( _key [ , _key ] .. )                                 Instance Class Helper Function: Allows resetting many key stored values to None on a single line.                                           In short: Calls this.Reset<Name>() for each name provided.

注意，由于数据类型或值的限制，一些数据没有被分配——这是有意为之。setter禁止分配错误的数据类型或值，甚至禁止将其分配为默认值(除非覆盖默认值保护行为)

代码没有发布在这里，因为在示例和解释之后我没有空间了……也因为它会改变。

请注意:在这个发布的时候，文件是混乱的-这将会改变。但是，如果你在Sublime Text中运行它并编译它，或者从Python中运行它，它将编译并输出大量信息- AccessorDB部分还没有完成(将用于更新Print getter和GetKeyOutput helper函数，同时被更改为一个实例函数，可能放入一个单独的函数并重命名-寻找它..)

其次:并不是运行它所需要的所有东西——底部的许多注释是用于调试的更多信息——当你下载它时，它可能不存在。如果是，您应该能够取消注释并重新编译以获得更多信息。

我正在寻找一个工作区，需要MyClassBase:通过，MyClass(MyClassBase):…如果你知道一个解决方案，把它贴出来。

类中唯一需要的是__行- str是用于调试的init -它们可以从演示类中删除，但你需要注释掉或删除下面的一些行(_foo / 2 / 3)..

顶部的String、Dict和Util类是我的Python库的一部分——它们不是完整的。我从图书馆复制了一些我需要的东西，并创建了一些新的东西。完整的代码将链接到完整的库，并将包括它以及提供更新的调用和删除代码(实际上，唯一剩下的代码将是演示类和打印语句- AccessorFunc系统将被移动到库)…

文件部分:

##
## MyClass Test AccessorFunc Implementation for Dynamic 1-line Parameters

class AccessorFuncDemoClassBase( ):
    pass
class AccessorFuncDemoClass( AccessorFuncDemoClassBase ):
    __Name      = AccessorFuncBase( parent = AccessorFuncDemoClassBase, name = 'Name',      default = 'AccessorFuncDemoClass',  allowed_types = ( TYPE_STRING ),                    allowed_values = VALUE_ANY,                 documentation = 'Name Docs',        getter_prefix = 'Get',  key = 'Name',       allow_erroneous_default = False,    options = { } )
    __x         = AccessorFuncBase( parent = AccessorFuncDemoClassBase, name = 'X',         default = 1111,                     allowed_types = ( TYPE_INTEGER, TYPE_FLOAT ),       allowed_values = VALUE_ANY,                 documentation = 'X Docs',           getter_prefix = 'Get',  key = 'x',          allow_erroneous_default = False,    options = { } )
    __Height    = AccessorFuncBase( parent = AccessorFuncDemoClassBase, name = 'Height',    default = 0,                        allowed_types = TYPE_INTEGER,                       allowed_values = VALUE_SINGLE_DIGITS,       documentation = 'Height Docs',      getter_prefix = 'Get',  key = 'Height',     allow_erroneous_default = False,    options = { } )

这种美感使得创建具有AccessorFuncs /回调/数据类型/值强制等动态添加属性的新类非常容易。

另外:如果你不使用Sublime Text，我推荐它优于notepad++， Atom, Visual Code和其他，因为适当的线程实现使它使用起来更快…我也在为它开发一个类似ide的代码映射系统-看看:https://bitbucket.org/Acecool/acecoolcodemappingsystem/src/master/(首先在包管理器中添加Repo，然后安装插件-当版本1.0.0准备好了，我会把它添加到主插件列表中…)

我希望这个解决方案能有所帮助……而且，一如既往:
