Python Coding challenge - Day 878| What is the output of the following Python Code?

 

Code Explanation:

1. Class Definition

class Item:

A class named Item is created.

It will represent an object that stores a price.

2. Initializer Method

    def __init__(self, p):

        self._p = p

Explanation:

__init__ is the constructor of the class.

It takes one argument p (the price).

The value is stored in a protected attribute _p.

_p means: "this is intended for internal use, but still accessible."

3. Property Decorator

    @property

    def price(self):

        return self._p + 10

Explanation:

@property turns the method price() into a read-only attribute.

Calling i.price will actually execute this method.

It returns self._p + 10, meaning:

The actual price returned is 10 more than the stored _p value.

4. Creating an Object

i = Item(50)

Explanation:

An instance of Item is created with _p = 50.

5. Accessing the Property

print(i.price)

Explanation:

Calls the price property.

Internally runs: return self._p + 10

_p = 50, so result = 60

Output

60
