Python : Data Encapsulation

The following table shows the different behaviour:

Name	Notation	Behaviour
name	Public	Can be accessed from inside and outside
_name	Protected	Like a public member, but they shouldn't be directly accessed from outside.
__name	Private	Can't be seen and accessed from outside

e.g.

class Account(object): 
    counter = 0
    def __init__(self, holder, number, balance,credit_line=1500): 
        Account.counter += 1
        self.__Holder = holder 
        self.__Number = number 
        self.__Balance = balance
        self.__CreditLine = credit_line
    def __del__(self):
        Account.counter -= 1
