Which means this topic definitely needs to be handled in detail by the
LR, and preferably also in the Tutorial. Otherwise there is no way

And by the way, the reason I've come across this problem at all is
because I have something like this:
class A:
class X:
n = 'a'
x = X()
class B(A):
class X(A.X):
n = 'b'
# x = X()
The line commented out was originally not there, but I found out I had

First of all, that's the LR for Python 2, I'm with Python 3. Second of
all, there's one single passage containing the phrase "method

Yes, I have no problem believing you guys that this is what Python
does. Still, my question remains about where in the Language Reference
this is specified. And if the

Sorta. I would expect B to have a copy of the "foo" attribute, which
then refers to the same method as A.foo. So the method itself will be
be copied, but its address stored separately in A.foo and B.foo.

You think I would have asked specifically about the Language Reference
if I hadn't read it and failed to find what I was looking for?
The closest thing I was able to find was section 3.2. "The standard

See, this is what tripped me up, right at the beginning. I thought B
would inherit (as in copy) the variable n from
