python question about classes

I have following two classes
Code:

## file_A.py
class A(object):
## a contains is instances of A
a= [ ] def __init__(self, node):
self.nodes_in_A = []
self.nodes_in_A.append(node) packet_queue = [ ] ...etc

## file_B.py
import A
class B(object):
## n contains instances of B
n = [ ] def some_func(self):
_len = len (A.A.a[0].packet_queue)
I get an error AttributeError: 'A' object has no attribute
'packet_queue'
Can you please explain me ...why ? and How to fix this ?
