this is happening on python 2.6 too.

Python 2.6.5 (r265:79063, Apr 16 2010, 13:57:41) [GCC 4.4.3] on linux2 Type "help", "copyright", "credits" or "license" for more information.

class Test(type): ... doc= File "", line 2 doc= ^ SyntaxError: invalid syntax class Test(type): ... doc='asasdas' ...

I don't get any syntax errors (Python2.7 and 2.6)

class Test(object): ... doc = "Something" ...

help(Test)

class Test(type): ... doc = "something" ... help(Test)

Test.doc 'something'

Test.doc='sadfsdff' Traceback (most recent call last): File "", line 1, in AttributeError: attribute 'doc' of 'type' objects is not writable type(Test) <type 'type'>

The name, bases, module, abstractmethods, dict and doc attributes have custom getters and setters in the type object definition. doc has only a getter. No setter and no deleter.

That is why you're seeing this. What's the question here?
