variable scope

[Joel Juvenal Rivera Rivera]

Hi i was playing around with my code the i realize of this

###################
_uno__a = 1
class uno():
__a = 2
def __init__(self):
print __a
uno()
###################
and prints 1

So when i create class uno in the __init__ calls the global _uno__a when
i refer just __a ? it's some kind of "private global" variable?

Regards
