8. Introduction to Polymorphism
● Polymorphism is a fundamental concept
in object-oriented programming (OOP).
● It refers to the ability of objects
to exhibit different behaviors based
on their data type or class.
13. DID YOU KNOW?
•In Python, polymorphism is primarily
achieved through duck typing.
•It focuses on the behavior of objects
rather than their types.
•Objects are considered to be of the
same type if they have compatible
methods and attributes.

14. DID YOU KNOW?
•Method overloading allows a class to
have multiple methods with the same
name but different parameters.
•Python does not support method
overloading directly, but it can be
achieved using default values or
variable-length arguments.

16. With inheritance
•Inheritance and polymorphism work
together, allowing objects of different
classes to respond differently to the
same method call based on their specific
types.
•Polymorphism can be achieved through
method overriding, where a subclass
provides its own implementation of a
method inherited from its parent class.
17. DID YOU KNOW?
• Achieve a form of interface-like
behavior by using abstract base
classes.
• The @0abstractmethod decorator
marks the method as abstract,
indicating that any class inheriting
from MyInterface must provide its
own implementation
of my_method().

18. Conclusion
Interface
•In Python, there is no explicit keyword for
defining interfaces like in some other
programming languages.
•However, interface-like behavior can be
achieved using abstract base classes .
•An interface defines a set of methods that a
class must implement to conform to the
interface.
•Abstract methods, marked with
the @abstractmethod decorator, serve as
placeholders for method definitions in the
interface.
•Classes that inherit from an interface must
provide implementations for all the abstract
methods.
19. Conclusion
Polymorphism
•Polymorphism is a fundamental concept
in object-oriented programming.
•It allows objects of different classes to be
treated as objects of a common base class,
enabling them to exhibit different
behaviors.
•Polymorphism is achieved through
method overriding, where a subclass
provides its own implementation of a
method inherited from its parent class.
•Method calls on objects are resolved at
runtime based on the actual object's type,
allowing different objects to respond
differently to the same method call.
•Polymorphism promotes code reusability,
flexibility, and extensibility by providing a
common interface for interacting with
diverse objects.
