The private access modifier is used to encapsulate attributes and methods within a class. Private attributes and methods are not accessible to subclasses and are intended to be used only within the class itself. They provide a way to hide implementation details and enforce encapsulation.

class Parent:
    __attribute = "Private"
  
    def get_from_parent(self):
        print(self.__attribute)

class Child(Parent):
    def get_from_child(self):
        print(self.__attribute)

instance = Child()
instance.get_from_parent()
instance.get_from_child() # AttributeError
copy

You can utilize parent methods to access parent private attributes/methods, which helps in reducing dependencies.

Python is a highly flexible programming language, allowing you to access private attributes using the following syntax:

instance._ClassName__attribute

But this is a BAD PRACTICE that specific syntax tells us.

Look at the example:


              
1234567

            
class SomeClass:
    __value = "Privated value"

instance = SomeClass()

print(instance._SomeClass__value)
print(SomeClass._SomeClass__value)
copy
