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
