[issue36156] different method, but id function return same value.

[lgj]

New submission from lgj <929102...@qq.com>:

>>> class A:
... def a(self):
... return 0
... def a1(self):
... return 1
...
>>> a =A()
>>> id(a.a)
4316559496
>>> id(a.a1)
4316559496
>>> id(a)
4318155272
It' seems oops , according to the id function source code.
here is the description of builtin_id function in Python/bltinmodule.c
/* 
Return the identity of an object.

This is guaranteed to be unique among simultaneously existing objects.
(CPython uses the object's memory address.)
[clinic start generated code]*

It seems should return different value, but id(a.a) as same as 
id(a.a1), Is it a bug?
