Overriding is a feature in object-oriented programming where a subclass provides a specific implementation of a method that is already defined in its superclass. This allows the subclass to modify or extend the behavior of the inherited method, providing more specialized functionality. Method overriding is a key aspect of polymorphism, as it allows an object to behave differently depending on its type.

Definition: Overriding allows a subclass to provide a specific implementation of a method that is already defined in its superclass.

For example, consider a class Animal with a method makeSound(). A subclass Dog might override makeSound() to provide a specific implementation that makes a “bark” sound. In this case, the Dog class uses the same method name as the superclass but with its own customized behavior.

class Animal:
    def sound(self):
        print("Some sound")
        
class Dog(Animal):
    def sound(self):
        print("Bark")

Method overriding helps in creating flexible and reusable code. It allows subclasses to take advantage of inherited methods while still tailoring behavior to suit their specific needs. Overriding is typically used in languages like Java, C++, and Python, and it plays an important role in implementing polymorphic behavior.
