programming python Python inheritance

Hướng dẫn which inheritance is not supported in python - thừa kế nào không được hỗ trợ trong python

Có, Python hỗ trợ nhiều kế thừa. Giống như C ++, một lớp có thể được lấy từ nhiều lớp cơ sở trong Python. Điều này được gọi là nhiều kế thừa.

Trong nhiều kế thừa, các tính năng của tất cả các lớp cơ sở được kế thừa vào lớp dẫn xuất. Hãy cho chúng tôi xem cú pháp -

Cú pháp

Class Base1:
	Body of the class

Class Base2:
	Body of the class

Class Base3:
	Body of the class
.
.
.
Class BaseN:
	Body of the class


Class Derived[Base1, Base2, Base3, … , BaseN]:
	Body of the class

Lớp dẫn xuất kế thừa từ cả Base1, Base2 và Base3Classes.

Thí dụ

Trong ví dụ dưới đây, lớp chim thừa hưởng lớp động vật.

  • Animal là lớp cha mẹ còn được gọi là siêu lớp hoặc lớp cơ sở.

  • Bird là lớp trẻ em còn được gọi là lớp phụ hoặc lớp có nguồn gốc.

Phương pháp class đảm bảo rằng Bird là một lớp con của lớp động vật.

class Animal:
	def eat[self]:
		print["It eats insects."]
	def sleep[self]:
		print["It sleeps in the night."]

class Bird[Animal]:
	def fly[self]:
		print["It flies in the sky."]

	def sing[self]:
		print["It sings a song."]
		print[issubclass[Bird, Animal]]

Koyal= Bird[]
print[isinstance[Koyal, Bird]]

Koyal.eat[]
Koyal.sleep[]
Koyal.fly[]
Koyal.sing[]

Đầu ra

True
It eats insects.
It sleeps in the night.
It flies in the sky.
It sings a song.
True

  • Câu hỏi và câu trả lời liên quan
  • Liệu kế thừa của MySQL hỗ trợ?
  • Java có hỗ trợ kế thừa lai không?
  • Java có hỗ trợ nhiều kế thừa không? Tại sao? Làm thế nào chúng ta có thể giải quyết điều này?
  • Python có hỗ trợ đa hình không?
  • Super [] của Python hoạt động như thế nào với nhiều kế thừa?
  • Làm thế nào để thừa kế lớp hoạt động trong Python?
  • C# và nhiều kế thừa
  • Java và nhiều kế thừa
  • Nhiều kế thừa trong C ++
  • Nhiều kế thừa trong JavaScript
  • JavaScript có hỗ trợ phạm vi khối không?
  • Selenium có hỗ trợ trình duyệt Safari không?
  • Làm thế nào chúng ta có thể mở rộng nhiều lớp Python trong kế thừa?
  • Nhiều kế thừa bằng giao diện trong Java
  • Sự khác biệt giữa đơn và nhiều kế thừa

Nhiều kế thừa thừa kế này cho phép một lớp con được thừa hưởng từ nhiều lớp cha mẹ. Loại kế thừa này không được hỗ trợ bởi các lớp Java, nhưng Python không hỗ trợ loại kế thừa này.inheritance in Python.

Python có hỗ trợ tất cả sự kế thừa không?

Kế thừa là một tính năng cần thiết của mọi ngôn ngữ lập trình hướng đối tượng. Điều này có nghĩa là Python hỗ trợ thừa kế và như bạn sẽ thấy sau này, đó là một trong số ít ngôn ngữ hỗ trợ nhiều kế thừa.

Loại kế thừa nào không được hỗ trợ? 

Để ngăn chặn tình huống như vậy, nhiều kế thừa không được phép trong Java.

Python hỗ trợ loại thừa kế nào?

Nhiều kế thừa thừa kế này cho phép một lớp con được thừa hưởng từ nhiều lớp cha mẹ.Loại kế thừa này không được hỗ trợ bởi các lớp Java, nhưng Python không hỗ trợ loại kế thừa này. This inheritance enables a child class to inherit from more than one parent class. This type of inheritance is not supported by java classes, but python does support this kind of inheritance.

Python có hỗ trợ tất cả sự kế thừa không?

Kế thừa là một tính năng cần thiết của mọi ngôn ngữ lập trình hướng đối tượng.Điều này có nghĩa là Python hỗ trợ thừa kế và như bạn sẽ thấy sau này, đó là một trong số ít ngôn ngữ hỗ trợ nhiều kế thừa.Python supports inheritance, and as you'll see later, it's one of the few languages that supports multiple inheritance.

Loại kế thừa nào không được hỗ trợ?

Để ngăn chặn tình huống như vậy, nhiều kế thừa không được phép trong Java.multiple inheritances is not allowed in java.

Tại sao thừa kế đa cấp không được hỗ trợ trong Python?

Nhiều kế thừa hữu ích trong nhiều tình huống như một nhà phát triển, nhưng nó làm tăng đáng kể sự phức tạp của ngôn ngữ, điều này làm cho cuộc sống khó khăn hơn cho cả nhà phát triển trình biên dịch và các lập trình viên.Một vấn đề xảy ra khi hai lớp cha có thành viên dữ liệu hoặc phương thức cùng tên.One problem occurs when two parent classes have data members or methods of the same name.
