Python OOPS Challenge | Day 15 | What is the output of following Python code?

The code snippet in the image is invalid and will raise an exception. Here's why:

Explanation:

1. Class TV Definition:

class TV:

    pass

A class TV is defined, but it has no attributes or methods.

2. Object Creation:

obj = TV()

An object obj is created from the TV class.

3. Dynamic Attribute Assignment:

obj.price = 200

A new attribute price is dynamically added to the obj instance, and its value is set to 200.

4. Invalid Access of self:

print(self.price)

The variable self is used outside of a method in the class, which is invalid.

In Python, self is a convention used as the first parameter of instance methods to refer to the calling instance. It cannot be used directly outside a method context.

What Happens:

When the Python interpreter reaches the print(self.price) statement, it will raise a NameError because self is not defined in the global scope.

Corrected Code (if you want to print the price):

To fix the code, the price attribute can be printed using the instance obj instead of self:

class TV:

    pass

obj = TV()

obj.price = 200

print(obj.price) # Outputs: 200

In this corrected version, obj.price correctly accesses the price attribute of the obj instance.
