python中get,getattr,getattribute的区别深入了解及应用

\_\_get\_\_,\_\_getattr\_\_和\_\_getattribute都是访问属性的方法，但不太相同。   
object.\_\_getattr\_\_(self, name)   
当一般位置找不到attribute的时候，会调用getattr，返回一个值或AttributeError异常。   
  
object.\_\_getattribute\_\_(self, name)   
无条件被调用，通过实例访问属性。如果class中定义了\_\_getattr\_\_()，则\_\_getattr\_\_()不会被调用（除非显示调用或引发AttributeError异常）   
  
object.\_\_get\_\_(self, instance, owner)   
如果class定义了它，则这个class就可以称为descriptor。owner是所有者的类，instance是访问descriptor的实例，如果不是通过实例访问，而是通过类访问的话，instance则为None。（descriptor的实例自己访问自己是不会触发\_\_get\_\_，而会触发\_\_call\_\_，只有descriptor作为其它类的属性才有意义。）（所以下文的d是作为C2的一个属性被调用）

1.  **class** C(object):  
2.      a = 'abc'  
3.      **def** \_\_getattribute\_\_(self, \*args, \*\*kwargs):  
4.          **print**("\_\_getattribute\_\_() is called")  
5.          **return** object.\_\_getattribute\_\_(self, \*args, \*\*kwargs)  
6.  \#        return "haha"  
7.      **def** \_\_getattr\_\_(self, name):  
8.          **print**("\_\_getattr\_\_() is called ")  
9.          **return** name + " from getattr"  
10.       
11.     **def** \_\_get\_\_(self, instance, owner):  
12.         **print**("\_\_get\_\_() is called", instance, owner)  
13.         **return** self  
14.       
15.     **def** foo(self, x):  
16.         **print**(x)  
17.   
18. **class** C2(object):  
19.     d = C()  
20. **if** \_\_name\_\_ == '\_\_main\_\_':  
21.     c = C()  
22.     c2 = C2()  
23.     **print**(c.a)  
24.     **print**(c.zzzzzzzz)  
25.     c2.d  
26.     **print**(c2.d.a)

输出结果是：

Python代码   ![收藏代码][icon_star.png]

1.  \_\_getattribute\_\_() **is** called  
2.  abc  
3.  \_\_getattribute\_\_() **is** called  
4.  \_\_getattr\_\_() **is** called   
5.  zzzzzzzz **from** getattr  
6.  \_\_get\_\_() **is** called <\_\_main\_\_.C2 object at 0x16d2310> <**class** '\_\_main\_\_.C2'>  
7.  \_\_get\_\_() **is** called <\_\_main\_\_.C2 object at 0x16d2310> <**class** '\_\_main\_\_.C2'>  
8.  \_\_getattribute\_\_() **is** called  
9.  abc

小结：可以看出，每次通过 实例 访问属性，都会经过\_\_getattribute\_\_函数。而当属性不存在时，仍然需要访问\_\_getattribute\_\_，不过接着要访问\_\_getattr\_\_。这就好像是一个异常处理函数。   
每次访问descriptor（即实现了\_\_get\_\_的类），都会先经过\_\_get\_\_函数。

需要注意的是，当使用类访问不存在的变量是，不会经过\_\_getattr\_\_函数。而descriptor不存在此问题，只是把instance标识为none而已。

来看看如何自定义实现gettattr让代码更加的动态优雅：

充分利用getattr会在没有查找到相应实例属性时被调用的特点，方便的通过链式调用生成对应的url，源代码中在碰到http method的时候返回一个  
可调用的对象更加的优雅，链式的操作不仅优雅而且还能很好的说明调用的接口的意义（restful的接口啦）。

**深入思考**  
既然能通过定制类的getattr自定义方法来实现一些优雅的功能，自然我们也要对它有一些了解，包括和它相似的自定义方法getattribute

**1. 用作实例属性的获取和拦截**  
当访问某个实例属性时， getattribute会被无条件调用，如未实现自己的getattr方法，会抛出AttributeError提示找不到这个属性，如果自定义了自己getattr方法的话，方法会在这种找不到属性的情况下被调用，比如上面的例子中的情况。所以在找不到属性的情况下通过实现自定义的getattr方法来实现一些功能是一个不错的方式，因为它不会像getattribute方法每次都会调用可能会影响一些正常情况下的属性访问：

**2. 自定义getattribute的时候防止无限递归**  
因为getattribute在访问属性的时候一直会被调用，自定义的getattribute方法里面同时需要返回相应的属性，通过self.\_\_dict\_\_取值会继续向下调用getattribute，造成循环调用：

[?][Link 1]

这里通过调用绑定的super对象来获取队形的属性，对新式类来说其实和object.\_\_getattribute\_\_(self, item)一样的道理:

默认情况下自定义的类会从object继承getattribute方法，对于属性的查找是完全能用的  
getattribute的实现感觉还是挺抽象化的，只需要绑定相应的实例对象和要查找的属性名称就行  
**3.同时覆盖掉getattribute和getattr的时候，在getattribute中需要模仿原本的行为抛出AttributeError或者手动调用getattr**
