Q.Which of the following is an example of identity operators of Python ?

Concept: Identity operators (is, is not) compare whether two objects refer to the same memory location, not just whether they are equal in value.

Step 1: Python has two identity operators: is and is not. They check object identity using id().

Step 2: Among the options:

• is — identity operator.
• on — not a Python operator. …

Concept and Intuition

In Python, every object lives somewhere in memory. When you create a variable, it holds a reference to that memory location. Two variables might hold the same value but point to different objects in memory — or they might point to the exact same object.

Identity operators (is and is not) answer the question: "Do these two names refer to the same object in memory?" This is different from the == operator, which checks whether the values are equal. For example, a == b could be True even when a is b is False, because Python might create two separate objects with the same value.

The other operators listed — in and not in — are membership operators, not identity operators. They check whether a value exists inside a container (like a list, string, or tuple). The option on is not a Python operator at all.

Step-by-Step Solution

1. Identify what Python identity operators are.

   Python has exactly two identity operators: is and is not. They return True if the two operands refer to the same object in memory, and False otherwise.

2. Examine each option against this definition.

   • (a) is — This is a valid identity operator. …
