Khi nào tôi nên sử dụng @property trong python?

Một tính năng trang trí trong Python bao bọc trong một hàm, nối thêm một số chức năng vào mã hiện có và sau đó trả về nó. Các phương thức và hàm được biết là có thể gọi được vì chúng có thể được gọi. Do đó, một trình trang trí cũng là một hàm có thể gọi được trả về có thể gọi được. Điều này còn được gọi là siêu lập trình vì tại thời điểm biên dịch, một phần của chương trình sẽ thay đổi phần khác của chương trình. Ghi chú. Để biết thêm thông tin, hãy tham khảo Trang trí trong Python

Trình trang trí Python @property

@property decorator là một công cụ trang trí tích hợp sẵn trong Python, rất hữu ích trong việc xác định các thuộc tính một cách dễ dàng mà không cần gọi thủ công hàm sẵn có property[]. Được sử dụng để trả về các thuộc tính thuộc tính của một lớp từ getter, setter và deleter đã nêu dưới dạng tham số. Bây giờ, hãy xem một số ví dụ để minh họa việc sử dụng trình trang trí @property trong Python. ví dụ 1.
