Python: Encapsulation

Sample program

class Animal:
    def __init__(self, Animalname):
        self.__Animalname = Animalname

    def name(self):
        return self.__Animalname



x = Animal("This")
print x.name()

t = Animal("Pet2")
print t.__Animalname

Output:

C:\Python27\python.exe E:/Scripts_to_learn/Scripts_to_learn/Encapsulation.py

This

Traceback (most recent call last):

  File "E:/Scripts_to_learn/Scripts_to_learn/Encapsulation.py", line 17, in <module>

    print t.__Animalname

AttributeError: Animal instance has no attribute '__Animalname'

Notes:

1. To make the attribute private, use "__". So that it can't be accessed from outside

2. To know/use the private attribute, create a method as above (Eg: Above 'name' method)
