- Even though Python does not explicitly support interfaces in the same way as some other languages, they play a pivotal role in structuring and organizing Python programs effectively. Here, interfaces aren't merely a language construct, but a design principle that helps improve code readability, maintainability, reusability, and testing.

Now, let us first understand what is an interface in Python. An interface in programming is a contract that defines the methods a class must implement. It specifies what methods a class should have but not how these methods should be implemented. This allows different classes to implement the interface in their own way, promoting flexibility and re...
Unlike some other programming languages, Python does not have a built-in interface keyword. Instead, Python uses abstract base classes (ABCs) from the abcmodule to define interfaces. An abstract base class can contain abstract methods that must be implemented by any subclass.
Let’s consider a real-world example: a vehicle registration system in the USA. We will define an interface for different types of vehicles, such as cars and motorcycles, and implement this interface in specific classes.
To further understand the power of interfaces, let’s expand our example to include a traffic management system. This system will manage different types of vehicles and ensure they follow traffic rules.
There are a lot of advantages of using interfaces in Python, here are a few. 1. Code Reusability: Interfaces allow you to define common functionality that can be reused across different classes. 2. Flexibility: Different classes can implement the same interface in their own way, providing flexibility in how functionality is achieved. 3. Maintainabi...
Interfaces in Python help you to write flexible, reusable, and maintainable code. By using abstract base classes from the abcmodule, you can define interfaces that specify the methods a class must implement. I hope the above two real-world examples gave you an idea of what an interface is in Python and how to use Python interfaces. You may also lik...
Jun 25, 2023 · At its core, an interface is a blueprint of a class. It is a contract that defines a set of methods that a class should implement. Consider an interface like an agreement between a class and the outside world. When a class implements an interface, it promises to provide specific behavior.

Interfaces play an important role in software engineering. As an application grows, updates and changes to the code base become more difficult to manage.
Interfaces in Python. In languages like Java and Go, there is keyword called interface which is used to define an interface. Python doesn't have it or any similar keyword. It uses abstract base classes (in short ABC module) and @abstractmethod decorator to create interfaces.
