Python Coding challenge - Day 897| What is the output of the following Python Code?

 

Code Explanation:

1. Defining a Class

class User:

This line defines a class named User.

A class is like a blueprint for creating objects.

2. Creating the Constructor Method

def __init__(self, name):

This is a constructor method.

It runs automatically when a new object is created from the class.

self → Refers to the current object.

 name → A parameter used to pass the user's name.

3. Initializing an Attribute

self.name = name

This line creates an instance variable called name.

It stores the value passed during object creation.

4. Creating an Object of the Class

u = User("Sam")

This creates an object u of the User class.

"Sam" is passed to the constructor and stored in u.name.

Now:

u.name → "Sam"

5. Adding a New Attribute Dynamically

u.score = 90

This adds a new attribute score to the object u.

Python allows adding new attributes to objects outside the class.

Now:

u.score → 90

6. Printing the Attribute Value

print(u.score)

This prints the value of the score attribute.

Output will be:

90

Final Output

90
