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 

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:
```python
instance._ClassName__attribute
```


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

Look at the example:

class SomeClass:
    __value = "Privated value"

instance = SomeClass()

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

This course covers Object-Oriented Programming (OOP) in Python, starting with the basics and progressing to advanced concepts. You will implement a User model to gain practical experience and understanding of OOP features. By the end of the course, you will have a strong foundation in OOP and a deeper knowledge of Python's inner workings.

Let's start! The Object-Oriented Programming basic concepts are waiting for you here! In this section, you will get acquainted with the most important concepts for understanding Object-Oriented Programming.

Inheritance - the first of the OOP principles. The entities can be inherited from other ones. You learn how it works in code here.

Inheritance - the second of the OOP principles. The attributes and methods can be closed inside the class and used by the class only. Here you learn how to code with different access modifiers.

Polymorphism and abstraction are the third and fourth of the OOP principles. These principles are not easy to understand. Here you will get to know them in the simplest ways.

The magic methods make sandbox from Python. It's a unique Python tool you can't see in other languages. Here you learn how to use these methods and about the flexibility that they bring to Python.
