Python Coding challenge - Day 854| What is the output of the following Python Code?

Code Explanation:

1. Class Definition

class Person:

This defines a new class named Person.

A class is a blueprint for creating objects.

Each object of this class can have its own attributes like name, age, etc.

2. Constructor Method

    def __init__(self, name):

        self.name = name

__init__ is the constructor method in Python.

It runs automatically when a new object of Person is created.

name is a parameter passed during object creation.

self.name = name assigns the value of name to the object’s attribute name.

3. Creating an Object

p = Person("Alice")

This creates an object p of class Person.

The constructor is called with name = "Alice".

The object now has an attribute p.name = "Alice".

4. Adding a Dynamic Attribute

p.age = 25

Here, a new attribute age is added dynamically to the object p.

Python allows adding attributes outside the constructor.

Now, p has two attributes: name = "Alice" and age = 25.

5. Accessing the Dynamic Attribute

print(p.age)

Accessing p.age retrieves the dynamically added attribute.

Python prints the value of age, which is:

Final Output:

25
