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 ?

Edit: 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.

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.

  1. 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

    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)
