UUID变体什么时候是整数？

Question

documentation on the uuid module 说：

UUID.variant ¶

The UUID variant, which determines the internal layout of the UUID. This will be one of the integer constants RESERVED_NCS, RFC_4122, RESERVED_MICROSOFT, or RESERVED_FUTURE.

以后：

uuid.RESERVED_NCS ¶

Reserved for NCS compatibility.

uuid.RFC_4122 ¶

Specifies the UUID layout given in RFC 4122.

uuid.RESERVED_MICROSOFT ¶

Reserved for Microsoft compatibility.

uuid.RESERVED_FUTURE ¶

Reserved for future definition.

鉴于此，我希望在访问这些属性时看到整数。然而：

>>> import uuid
>>> u = uuid.uuid4()
>>> u.variant
'specified in RFC 4122'
>>> uuid.RESERVED_NCS
'reserved for NCS compatibility'
>>> uuid.RFC_4122
'specified in RFC 4122'
>>> uuid.RESERVED_MICROSOFT
'reserved for Microsoft compatibility'
>>> uuid.RESERVED_FUTURE
'reserved for future definition'

这在 2.7.9 和 3.4.2 中产生了相同的结果，我还没有找到任何版本的文档表明这些常量可能是字符串。

我能在这个问题上产生的最相关的搜索结果恰好是该模块的源代码（在 SVN or GitHub 上），其中包含以下语句：

RESERVED_NCS, RFC_4122, RESERVED_MICROSOFT, RESERVED_FUTURE = [

    'reserved for NCS compatibility', 'specified in RFC 4122',
    'reserved for Microsoft compatibility', 'reserved for future definition']

考虑到我在解释器中看到的结果，这是完全有道理的，但我不能对文档说同样的话。

这是一个简单的文档错误，还是在某些地方这些属性确实是整数，正如文档所承诺的那样？这是怎么回事？

Answer 1

这是文档中的错误。我在 official bug tracker 中提交了它，并且已通过删除单词 "integer":

来修复它

I simply remove the type description since I think the type of the constants doesn't matter here.
