It seems to produce the output you expected for me (Python 2.4.1 on Windows
XP), but this has nothing to do with "carol". How are bob and carol related?
Code:
class bob(object):
def __init__(self):
print self.x
x = 2
class carol(object):
def __new__(cls):
return b
b=bob()
print b.x
c = carol()
c
Output:
>>>
2
2
This code produces the same output:
class bob(object):
def __init__(self):
print self.x
x = 2
## class carol(object):
## def __new__(cls):
## return b
b=bob()
print b.x
## c = carol()
##c
I am interested in the underlying subject but think your code was mispasted
into the e-mail...
