Private and Public Concepts
Encapsulation provides access to the methods and attributes of the class.
Private or public
Some attributes and/or methods cannot be accessed or modified. For example, it is correct not to change the number_of_legs of your cat object (usually, this value is 4).
This attribute must be private - not available outside the class.
By default, all methods and attributes are public in the Python class.
To make it private, add two __ before the variable name:
12345678class Cat: def __init__(self, name = 'Kitty', age = 1): self.name = name self.age = age # Private self.__number_of_legs = 4 print(Cat)
The way to access even the private value:
12345678910class Cat: def __init__(self, name = 'Kitty', age = 1): self.name = name self.age = age # Private self.__number_of_legs = 4 cat = Cat() # Access the private value print(cat._Cat__number_of_legs)
