Polymorphism in Python in Hindi
What is Polymorphism in Python
Polymorphism, Object-Oriented Programming का एक concept है, python classes and objects programming मे जब एक function, method या operator different contexts मे different types के objects के साथ काम करता है तो इस concept को polymorphism कहते है।
Key Concepts of Polymorphism
Method Overriding: Polymorphism मे method overriding तब होता है जब child class अपने parent class के method को redefine कर देता है।
Method Overloading: जब एक ही class मे multiple methods, same name लेकिन different parameters के साथ होते है तब Method Overriding होती है।
Operator Overloading: Python मे operators को objects के साथ differently behave करने के लिए redefine कर सकते है।
Types of Polymorphism
Polymorphism with Functions and Objects
Python मे हम एक single function को different types के objects के साथ use कर सकते है, ये इस बात पर depend करता है कि object का class क्या provide करता है।
Example 1.py
Copy to clipboard
class Cat:
def sound(self):
return "Meow"
class Dog:
def sound(self):
return "Bark"
def make_sound(animal):
print(animal.sound())
cat = Cat()
dog = Dog()
make_sound(cat) # Output: Meow
make_sound(dog) # Output: Bark
Polymorphism with Inheritance
Inheritance के through polymorphism को achive कर सकते है जहां child class अपने parent class के method को override करता है।
Example 2.py
Copy to clipboard
class Animal:
def sound(self):
raise NotImplementedError("Subclass must implement abstract method")
class Cat(Animal):
def sound(self):
return "Meow"
class Dog(Animal):
def sound(self):
return "Bark"
animals = [Cat(), Dog()]
for animal in animals:
print(animal.sound())
Operator Overloading
Operator Overloading मे operator different objects के साथ different types से behave करता है, इसे हम methods के through achieve कर सकते है।
Example 3.py
Copy to clipboard
class Point:
def __init__(self, x, y):
self.x = x
self.y = y
def __add__(self, other):
return Point(self.x + other.x, self.y + other.y)
def __str__(self):
return f"({self.x}, {self.y})"
p1 = Point(1, 2)
p2 = Point(3, 4)
print(p1 + p2) # Output: (4, 6)
