Explanation

- An **interface** in Python is typically implemented using an **abstract base class (ABC)**. It defines a contract for subclasses: they must implement the methods defined in the interface. An interface only specifies method signatures, but doesn't provide any implementation.
- Python doesn’t have explicit interfaces like Java or C#. Instead, we use **abstract classes** with abstract methods to mimic the behavior of interfaces.

Steps

• Define an abstract base class with abstract methods using ABC and abstractmethod.
• Create subclasses that inherit the abstract base class and implement the abstract methods.

from abc import ABC, abstractmethod
 
class Vehicle(ABC):  # Interface (Abstract Base Class)
    @abstractmethod
    def start(self):
        pass
 
class Car(Vehicle):  # Concrete class
    def start(self):
        print("Car is starting.")
 
car = Car()
car.start()  # Output: Car is starting.
