n Python, unlike some other programming languages, there is no explicit syntax for defining interfaces. However, you can create a similar concept by defining an abstract base class (ABC) that contains abstract methods. An abstract method is a method that is declared in a base class, but has no implementation. Subclasses of the abstract base class must implement these abstract methods.

Here’s an example:

from abc import ABC, abstractmethod

class Shape(ABC):
    @abstractmethod
    def area(self):
        pass

class Square(Shape):
    def __init__(self, side):
        self.side = side

    def area(self):
        return self.side * self.side

square = Square(5)
print(square.area())  # 25

In the example above, the Shape class is defined as an abstract base class using the ABC class from the abc module.

The area method is defined as an abstract method using the @abstractmethod decorator. The Square class is a concrete implementation of the Shape interface, and implements the area method. When you create an instance of the Square class and call its area method, the implementation of the area method in the Square class is executed, and the result is returned.
