What is the difference between operator overloading and inheritance in Python?
Operator overloading allows you to define custom behavior for operators (like +, -, etc.) in your classes, while inheritance lets you create a new class based on an existing class, inheriting its properties and methods.
Can you give me an example of operator overloading?
Sure! Here's a simple example:
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)
p1 = Point(1, 2)
p2 = Point(3, 4)
result = p1 + p2 # Uses the __add__ method
And how does inheritance work in Python?
Inheritance allows a class (child class) to inherit attributes and methods from another class (parent class). For example:
class Animal:
def speak(self):
return "Animal speaks"
class Dog(Animal):
def speak(self):
return "Woof!"
dog = Dog()
print(dog.speak()) # Outputs: Woof!"
Which one is better to use in a given situation?
It depends on the use case. Use operator overloading for custom behavior with operators, and inheritance for code reuse and creating a hierarchy of classes.
