Python Coding challenge - Day 855| What is the output of the following Python Code?

 

Code Explanation:

1. Base Class Definition

class A:

This defines a class named A.

Class A will contain a class variable and a method.

2. Class Variable in Class A

    x = 5

x is a class variable, meaning it belongs to the class itself, not individual objects.

All instances of class A share this value unless overridden.

3. Method in Class A

    def get(self):

        return self.x

This method returns the value of self.x.

Python first checks instance attributes, then class attributes, following the attribute lookup chain.

If the object belongs to a subclass (like B), Python also checks subclass attributes.

4. Subclass Definition

class B(A):

Class B inherits from class A.

That means B gets A’s variables and methods unless it overrides them.

5. Overriding the Class Variable

    x = 10

Class B defines its own class variable x = 10.

This overrides A’s x = 5 for any object created from B.

6. Creating an Object of B

b = B()

An instance b of class B is created.

It inherits the method get() from class A.

The class variable x for this instance comes from class B, not A.

7. Calling the Method

print(b.get())

This calls get() from class A.

Inside get(), self.x refers to the attribute x of object b.

Since b belongs to class B, it uses B.x = 10, not A.x = 5.

So the output is:

10

✅ Final Output

10
