Two classes problem

[Gurpreet Sachdeva]

I have two classes;

a.py -->

#!/usr/bin/python
global test
test =''
class a(b):
        def __init__(self,test):
                print test
print 'Outside: '+test

b.py -->

#!/usr/bin/python
import a
a.a('Garry')

I want to pass this string (or any object later) to a.py and that too
outside the scope of class a.
Is that possible??? If yes, how???

Thanks,

Garry
