This article mainly introduces how to use the python abstract class, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

Description

1. Abstract classes are used to simplify complex reality by modeling classes suitable for the problem, one of which cannot be instantiated.

2. It means that objects or instances cannot be created for these classes. Abstract classes can only be used to inherit functions called base classes.

So you can inherit functionality, but you cannot create an instance of this particular class at the same time.

Example

From abc import ABC, abstractmethod class Employee (ABC): @ abstractmethod def calculate_salary (self,sal): pass class Developer (Employee): def calculate_salary (self,sal): finalsalary= sal*1.10 return finalsalary emp_1 = Developer () print (emp_1.calculate_salary (10000)

As you can see from the output above, we have raised the base salary to 10%, that is, the current salary is 11000. Now, if you do continue to create an object of an Employee class, it will throw an error because python does not allow you to create an object of an abstract class. But if you use inheritance, you can actually inherit properties and perform the corresponding tasks.

Thank you for reading this article carefully. I hope the article "how to use python Abstract classes" shared by the editor will be helpful to everyone. At the same time, I also hope that you will support us and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
