Undefined.

This is due to hoisting. The code behaves like this 👇

var a; //the variable got hoisted
console.log(a); // Outputs: undefined
a = 5;

[We know when a declare a variable the initial value is "undefined" until we assign a value]

Answer: Exception

Solution:
class TV:
pass
creates a new data type called TV.

pass is just a no-operation statement, it doesn't add any data or functionality to the class.

Hence, this data type does not contain any attributes or functionality

obj = TV()
creates a new object named obj, of the data type TV.

obj.price = 200
creates a new variable named price, within obj.
The value of this variable is set to 200.

Finally, we have
print(self.price)

But there is no object named self here!

Hence, we get an Exception stating that there is nothing called self.

But you'd have seen self in other programs elsewhere.

self is not a keyword or pre-defined variable in Python.

It is simply a convention to use self WITHIN methods to denote

the first parameter of the method.

The first parameter of a method is is the object through which the method was invoked.

Eg.
a = [1,2,3]
then
a.append(5)
is equivalent to
list.append(a, 5)

So here, a is implicitly passed to the method append.

The name self is

conventionally used to refer to the implicit argument passed in methods.

Otherwise, the word self has no special meaning in Python.

Hence, the code in the question gives an error, because self is not defined before use.

I hope this helped!
