Lớp python không được định nghĩa bên trong lớp

Python là một ngôn ngữ lập trình hướng đối tượng, mọi thứ trong python đều liên quan đến các đối tượng, phương thức và thuộc tính. Một lớp là một bản thiết kế do người dùng định nghĩa hoặc một nguyên mẫu mà chúng ta có thể sử dụng để tạo các đối tượng của một lớp. Lớp được định nghĩa bằng cách sử dụng từ khóa lớp

Ví dụ về lớp học

Python3

# create a Geeksforgeeks class

class Geeksforgeeks :

   gfg

Name: Green
Name: Light Green
Code: 024avc

0

Name: Green
Name: Light Green
Code: 024avc

1

Trước hết, chúng ta phải hiểu phương thức có sẵn __init__() để hiểu ý nghĩa của các lớp. Bất cứ khi nào lớp được bắt đầu, một phương thức cụ thể là __init__() luôn được thực thi. Phương thức __init__() được sử dụng để gán giá trị cho thuộc tính đối tượng hoặc để thực hiện phương thức khác được yêu cầu hoàn thành khi đối tượng được tạo

Ví dụ. lớp với phương thức __init__()

Lớp bên trong Python

Một lớp được định nghĩa trong một lớp khác được gọi là lớp bên trong hoặc lớp lồng nhau. Nếu một đối tượng được tạo bằng cách sử dụng lớp con có nghĩa là lớp bên trong thì đối tượng đó cũng có thể được sử dụng bởi lớp cha hoặc lớp gốc. Một lớp cha có thể có một hoặc nhiều lớp bên trong nhưng thường tránh các lớp bên trong

Chúng ta có thể làm cho mã của mình hướng đối tượng hơn nữa bằng cách sử dụng một lớp bên trong. Một đối tượng duy nhất của lớp có thể chứa nhiều đối tượng con. Chúng ta có thể sử dụng nhiều đối tượng con để tạo cấu trúc tốt cho chương trình của mình

Ví dụ

• Đầu tiên, chúng ta tạo một lớp và sau đó tạo hàm tạo của lớp
• Sau khi tạo một lớp, chúng ta sẽ tạo một lớp khác bên trong lớp đó, lớp bên trong một lớp khác sẽ được gọi là lớp bên trong

Tại sao lớp bên trong?

Đối với nhóm của hai hoặc nhiều lớp. Giả sử chúng ta có hai lớp điều khiển từ xa và pin. Mọi điều khiển từ xa đều cần có pin nhưng điều khiển không có pin sẽ không được sử dụng. Vì vậy, chúng tôi biến Pin thành lớp bên trong của Điều khiển từ xa. Nó giúp chúng tôi lưu mã. Với sự trợ giúp của lớp bên trong hoặc lớp lồng nhau, chúng ta có thể ẩn lớp bên trong với thế giới bên ngoài. Do đó, Ẩn mã là một tính năng tốt khác của lớp bên trong. Bằng cách sử dụng lớp bên trong, chúng ta có thể dễ dàng hiểu các lớp vì các lớp có liên quan chặt chẽ với nhau. Chúng ta không cần phải tìm kiếm các lớp trong toàn bộ mã, tất cả chúng gần như cùng nhau. Mặc dù các lớp bên trong hoặc lớp lồng nhau không được sử dụng rộng rãi trong Python, nhưng nó sẽ là một tính năng tốt hơn để triển khai mã vì nó dễ tổ chức khi chúng ta sử dụng lớp bên trong hoặc lớp lồng nhau

cú pháp

________số 8_______

Các loại lớp bên trong như sau.  

1. Nhiều lớp bên trong
2. Lớp bên trong đa cấp

Nhiều lớp bên trong

Lớp chứa một hoặc nhiều lớp bên trong được gọi là nhiều lớp bên trong. Chúng ta có thể có nhiều lớp bên trong trong một lớp, dễ dàng triển khai nhiều lớp bên trong.  

Ví dụ. Nhiều lớp bên trong

Lớp bên trong đa cấp

Lớp chứa một lớp bên trong và lớp bên trong đó lại chứa một lớp bên trong khác, hệ thống phân cấp này được gọi là lớp bên trong đa cấp

Làm cách nào để xác định một lớp trong Python?

Khi một hàm được định nghĩa bên trong một lớp trong Python?

Tại sao bản thân không hoạt động trong Python?

Tên gọi khác của một hàm được định nghĩa bên trong một lớp là gì?
