...and really means this...
class C:
x = 1
def f(self,y): return T.x + y
I don't understand what T is. Did you mean C?
Yes, I meant C. Thanks.
If so, you are wrong. self.x is not the same as class.x due to
inheritance rules. Consider one example:
example snipped see thread/
I think a big part of the problem is that the scoping rules in Python
are inconsistent because classes are a different kind of object. An
example helps:
This works:
x = 1
def f(y): return y + x
This works:
def f():
x = 1
def g(y): return x + y
return g(2)
But this doesn't work...

Hi Arnaud et al,
Here is the link to the bug report from which the discussion in PEP
289 was extracted:

It looks like they were fixing a bunch of bugs and that this
discussion was one of the many in that thread.
Here is another post which points to the core

Hello,
Can someone help me understand what is wrong with this example?
class T:
A = range(2)
B = range(4)
s = sum(i*j for i in A for j in B)
It produces the exception:
type 'exceptions.NameError': global name 'j' is not defined

Hi Folks,
Thanks everyone for the great contributions! I understand this better
now. The distinction between a shorthand for a function definition and
a shorthand for a loop iteration is crucial.
Also: thanks for pointing out the even the list comprehension doesn't
work in py3. That was
