我觉得简单的答案是：不，斌（）不能超载像十月（）和十六进制（）。

I think the short answer is 'No, bin() can't be overloaded like oct() and hex().'

至于为什么，答案必须位于与Python 3.0，它使用 __指数__ 超载十六进制（）， 十月（）和斌（），并已删除了 __月__ 和 __ __（十六进制）特殊功能完全。

As to why, the answer must lie with Python 3.0, which uses __index__ to overload hex(), oct() and bin(), and has removed the __oct__ and __hex__ special functions altogether.

所以，Python的2.6 斌（）看起来非常像这真是一个Python 3.0的功能，一直没有，它的处事新的Python 3太多的考虑后移植方式，而不是旧的Python 2路。我还猜想，它不可能得到固定，即使它被认为是一个错误。

So the Python 2.6 bin() looks very much like it's really a Python 3.0 feature that has been back-ported without much consideration that it's doing things the new Python 3 way rather than the old Python 2 way. I'd also guess that it's unlikely to get fixed, even if it is considered to be a bug.
