**Encapsulation** is one of the fundamental concepts of object-oriented programming (OOP). It refers to the ability to store information inside a class with limited access.

# Access Types
There are different access types for attributes and methods:

- **Public**: Attributes/Methods that can be accessed and used both inside and outside the class.
- **Protected**: Attributes/Methods that are intended to be used within the class and its subclasses. They are indicated by a single underscore prefix, such as `_attribute` or `_method`.
- **Private**: Attributes/Methods that are intended to be used only within the class and cannot be accessed or used from outside the class. They are indicated by a double underscore prefix, such as `__attribute` or `__method`.

# Syntax
Access types in Python are implemented simply. You can create attributes/methods with addition marks:

```python
class SomeClass:
    attribute = "Public"
    _attribute = "Protected"
    __attribute = "Private"
    
    def method(self):
        print("Public method")
        
    def _method(self):
        print("Protected method")

    def __method(self):
        print("Private method")
```

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.
