Which of the following special methods is used for overloading the addition operator? __add____plus____sum____addition__

Correct Method for Overloading the Addition Operator

The special method used for overloading the addition operator in Python is __add__.

1. Operator Overloading: In Python, operator overloading allows you to define how operators behave for user-defined classes.
2. The Special Method: The __add__ method is explicitly designed to overload the addition operator (+). When you define this method in your class, you can control how instances of your class are added together.
3. Example: For example:

   class Vector:
       def __init__(self, x, y):
           self.x = x
           self.y = y
       
       def __add__(self, other):
           return Vector(self.x + other.x, self.y + other.y)
   
   v1 = Vector(1, 2)
   v2 = Vector(3, 4)
   v3 = v1 + v2  # This will call v1.__add__(v2)
   

Summary

In conclusion, to overload the addition operator in Python, you use the __add__ method. The other options listed (__plus__, __sum__, __addition__) are not valid for this purpose.
