bookPrivate 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:


              
12345678

            
class Cat:
  def __init__(self, name = 'Kitty', age = 1):
    self.name = name
    self.age = age
    # Private 
    self.__number_of_legs = 4

print(Cat)
copy

The way to access even the private value:


              
12345678910

            
class 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)
copy
