Question

这是一个基本的Python问题。很久以前我看到过这样的东西，我相信它是在Python中。是可能的，还是我错了？

我想要办法做到这一点;下面的例子只是虚构的代码，说明它是如何工作的，但不是。

class SomeClass:
    def someMethod(self):
        return self.name + ' ' + self.id

    name = 'A name'
    id = '37'
    fullClassName = someMethod  # reading this attribute would actually call the method

>>> a = SomeClass()
>>> print a.fullClassName  # no parentheses as it's not a method call
A name 37

Answer 1

您正在寻找property。

>>> class SomeClass:
...     name = 'A name'
...     id = '37'
...
...     @property
...     def someMethod(self):
...         return self.name + ' ' + self.id
...
...     fullClassName = someMethod
...
>>> a = SomeClass()
>>> print a.fullClassName
A name 37
>>>

或只是

>>> class SomeClass:
...     name = 'A name'
...     id = '37'
...
...     @property
...     def fullClassName(self):
...         return self.name + ' ' + self.id
...
>>> a = SomeClass()
>>> print a.fullClassName
A name 37
>>>
