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 Show 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. con trănThe value of the temperature is set.

ValueError: It is a value error.80 đầu ra. The value of the temperature is set.

ValueError: It is a value error. Ở đây, một lỗi giá trị được đưa ra vì giá trị của nhiệt độ được chỉ định phải trên -273. Nhưng đây là -300. Do đó, một lỗi giá trị được đưa ra Phương thức @property trong Python là gì?Người trang trí @property
. Cú pháp của hàm này là. property(fget=None, fset=None, fdel=None, doc=None) trong đó, fget là hàm lấy giá trị của thuộc tính. fset là chức năng để đặt giá trị của thuộc tính. a built-in function that creates and returns a property object. The syntax of this function is: property(fget=None, fset=None, fdel=None, doc=None) where, fget is function to get value of the attribute. fset is function to set value of the attribute.
Sự khác biệt giữa thuộc tính và thuộc tính trong Python là gì?Các thuộc tính được mô tả bởi các biến dữ liệu, ví dụ như tên, tuổi, chiều cao, v.v. Thuộc tính là loại thuộc tính đặc biệt có các phương thức getter, setter và delete như các phương thức __get__, __set__ và __delete__.
Bạn có nên sử dụng getters và setters trong Python không?Mặc dù mẫu getter và setter khá phổ biến trong các ngôn ngữ lập trình khác, nhưng đó không phải là trường hợp trong Python. Việc thêm các phương thức getter và setter vào lớp học của bạn có thể làm tăng đáng kể số dòng trong mã của bạn .
lợi ích của việc sử dụng trong trang trí là gì?Trình trang trí có thể cực kỳ hữu ích vì chúng cho phép mở rộng chức năng hiện có mà không cần sửa đổi mã nguồn gốc của chức năng . |
