Python Coding challenge - Day 881| What is the output of the following Python Code?

 

Code Explanation:

1. Class Definition

class Alpha:

A new class Alpha is created.

This class will support custom addition using __add__.

2. Constructor Method

def __init__(self, a):

    self.__a = a

__init__ runs whenever an object is created.

self.__a is a private variable because it starts with __.

3. Overloading the + Operator

def __add__(self, other):

    return Alpha(self.__a - other.__a)

This method defines what happens when we write object1 + object2.

Instead of adding, this code subtracts the internal values.

It returns a new Alpha object with the computed value.

4. Creating Objects

x = Alpha(10)

y = Alpha(4)

x stores a private value __a = 10.

y stores a private value __a = 4.

5. Using the Overloaded + Operator

z = x + y

Calls Alpha.__add__(x, y)

Computes 10 - 4 = 6

Stores result inside a new Alpha object, assigned to z.

6. Printing the Type

print(type(z))

z is an object created by Alpha(...)

So output is:

Output

<class '__main__.Alpha'>
