Python là 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 bản thiết kế do người dùng xác định hoặc nguyên mẫu mà chúng ta có thể sử dụng để tạo các đối tượng của một lớp. Lớp được xác định bằng cách sử dụng từ khóa lớp.is an Object-Oriented Programming Language, everything in python is related to objects, methods, and properties. A class is a user-defined blueprint or a prototype, which we can use to create the objects of a class. The class is defined by using the class keyword. Show
Ví dụ về lớp học Python3
Name: Green Name: Light Green Code: 024avc0 Trước hết, chúng ta phải hiểu phương pháp tích hợp __init __ () để hiểu ý nghĩa của các lớp. Bất cứ khi nào lớp được bắt đầu, một phương thức là __init __ () luôn được thực thi. Phương thức __init __ () được sử dụng để gán các giá trị cho các thuộc tính đối tượng hoặc để thực hiện phương thức khác cần thiết để hoàn thành khi đối tượng được tạo. Ví dụ: Lớp có phương thức __init __ ()class with __init__() method Python3

Nếu một đối tượng được tạo bằng cách sử dụng lớp bên trong lớp con thì đối tượng 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 nhìn chung các lớp bên trong được tránh.inner class or nested class. If an object is created using child class means inner class then the object can also be used by parent class or root class. A parent class can have one or more inner classes but generally inner classes are avoided. Chúng ta có thể làm cho mã của chúng ta trở nên định hướng đối tượng hơn bằng cách sử dụng một lớp bên trong. Một đối tượng duy nhất của lớp có thể chứa nhiều đối tượng phụ. Chúng tôi có thể sử dụng nhiều đối tượng phụ để cung cấp một cấu trúc tốt cho chương trình của chúng tôi. Example:

Name: Green Name: Light Green Code: 024avc19Tại sao lớp bên trong? Cho nhóm hai hoặc nhiều lớp. Giả sử chúng ta có hai lớp từ xa và pin. Mỗi điều khiển từ xa đều cần một pin nhưng pin không có won từ xa được sử dụng. Vì vậy, chúng tôi làm cho pin trở thành một lớp bên trong đến điều khiển từ xa. Nó giúp chúng tôi lưu mã. Với sự giúp đỡ của lớp bên trong hoặc lớp lồng nhau, chúng ta có thể che giấu lớp bên trong khỏi 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. Chúng tôi không cần phải tìm kiếm các lớp trong toàn bộ mã, tất cả đều gần như cùng nhau. Mặc dù các lớp bên trong hoặc lồng nhau không được sử dụng rộng rãi trong Python, nhưng nó sẽ là một tính năng tốt hơn để thực hiện mã vì việc tổ chức khi chúng ta sử dụng lớp bên trong hoặc lớp lồng nhau.Multiple inner class Python3Các loại lớp bên trong như sau: & nbsp; This is an outer class This is the inner class This is an inner class of inner class7 Name: Green Name: Light Green Code: 024avc3 Name: Green Name: Light Green Code: 024avc4 Name: Green Name: Light Green Code: 024avc5 Name: Green Name: Light Green Code: 024avc6

Vì vậy, bạn có thể nhanh chóng tạo một thể hiện của lớp bên trong và thực hiện các hoạt động trong lớp bên ngoài khi bạn thấy phù hợp. Tuy nhiên, bạn không thể truy cập lớp bên ngoài trong một lớp bên trong.. So, you can quickly create an instance of the inner class and perform operations in the outer class as you see fit. You can't, however, access the outer class in an inner class.
Làm thế nào để bạn gọi một lớp trong lớp khác?Họ được truy cập bằng tên lớp kèm theo.Để khởi tạo một lớp bên trong, trước tiên bạn phải khởi tạo lớp bên ngoài.Sau đó, tạo đối tượng bên trong bên trong đối tượng bên ngoài với cú pháp này: Lớp bên ngoài.using the enclosing class name. To instantiate an inner class, you must first instantiate the outer class. Then, create the inner object within the outer object with this syntax: OuterClass.
Tôi có thể làm tổ các lớp học trong Python không?Một trong những tính năng hữu ích và mạnh mẽ nhất của Python là khả năng làm tổ của nó trong các lớp học.Một lớp lồng nhau là một lớp được xác định trong một lớp khác và kế thừa tất cả các biến và phương thức của lớp cha.. A nested class is a class defined within another class, and inherits all the variables and methods of the parent class.
Làm thế nào để bạn gọi một phương thức bên trong một lớp học trong Python?Sử dụng self.f () để gọi một phương thức lớp bên trong __init__ trong định nghĩa phương thức của __init __ (tự), hãy gọi tự.f () trong đó f là tên của phương thức lớp. f() to call a class method inside of __init__
Within the method definition of __init__(self) , call self. f() where f is the name of the class method. |
