`@property` is a decorator that modifies the method inside a class to the class property.

To create the **property**, you should create a method with the `@property` decorator above.

class CinemaHall:
    def __init__(self, rows, seats_in_row):
        self.rows = rows
        self.seats_in_row = seats_in_row

    @property
    def capacity(self):
        return self.rows * self.seats_in_row

hall = CinemaHall(24, 12)
print(hall.capacity)

hall.rows = 5
hall.seats_in_row = 11
print(hall.capacity)

In the example above, you can see a cinema hall that has attributes `rows` and `seats_in_row`. The `capacity` property returns the total number of seats in the hall. It wouldn't make sense to create a separate attribute `capacity` because if we change the number of `rows`, we would have conflicting values. Specifically, no actions are performed with the class; only one of the hall's properties is returned.

Properties should have a specific logic: they should return a certain attribute of the class, unlike methods that are used to perform specific actions with the class.

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.
