Python Coding challenge - Day 1068| What is the output of the following Python Code?

 

Code Explanation:

1. Defining Class A

class A:

Explanation:

This line creates a class named A.

A class is a blueprint for creating objects.

2. Defining Method f

def f(self):

    return "A"

Explanation:

A method f is defined inside class A.

self refers to the current object (instance) of the class.

The method returns the string "A" when called.

So the class now contains a method:

A.f() → returns "A"

3. Creating an Object

a = A()

Explanation:

This creates an object a of class A.

Now a can access the class methods and attributes.

Example:

a.f()  → "A"

4. Assigning a New Attribute to the Object

a.f = "value"

Explanation:

Here we assign "value" to a.f.

This creates an instance attribute f inside object a.

In Python, instance attributes override class attributes or methods with the same name.

So now:

a.f → "value"

The original method f in class A is shadowed (hidden) by the instance variable.

5. Printing the Value

print(a.f)

Explanation:

Python first looks for attribute f inside the object a.

It finds a.f = "value".

Therefore it prints "value", not the method.

6. Final Output

value
