Python对象属性 - 方法访问 [英] Python object attributes - methodology for access

问题描述

假设我有一些属性的类。它是如何最好（在Python化，OOP）意识来访问这些属性？就像 obj.attr ？或许写get访问？
什么是这样的事情接受的命名风格？

Suppose I have a class with some attributes. How is it best (in the Pythonic-OOP) sense to access these attributes ? Just like obj.attr ? Or perhaps write get accessors ? What are the accepted naming styles for such things ?

编辑：
你能否解释与单或双下划线命名属性的最佳实践？我看到在一个单一的下划线最常用的模块。

Can you elaborate on the best-practices of naming attributes with a single or double leading underscore ? I see in most modules that a single underscore is used.

如果这个问题已经问（我有它有一种预感，虽然搜索并没有带来的结果），请指向它 - 我会关闭这一个。

If this question has already been asked (and I have a hunch it has, though searching didn't bring results), please point to it - and I will close this one.

推荐答案

做事的普遍接受的方法就是使用简单的属性，像这样

The generally accepted way of doing things is just using simple attributes, like so

>>> class MyClass:
...     myAttribute = 0
... 
>>> c = MyClass()
>>> c.myAttribute 
0
>>> c.myAttribute = 1
>>> c.myAttribute
1

如果你发现自己需要能够写getter和setter，那么你要寻找什么是Python类属性，的瑞安Tomayko对第
getter / setter方法​​/ Fuxors 是一个伟大的地方开始（虽然有点长）

If you do find yourself needing to be able to write getters and setters, then what you want to look for is "python class properties" and Ryan Tomayko's article on Getters/Setters/Fuxors is a great place to start (albeit a little long)
