12.2.5 Identity Operator
Identity operators are used to determine whether two variables point to the same object in memory. They do not
compare the actual values of the objects; instead, they check if both variables refer to the exact same location. The
result of an identity operation is always either True or False.
Python has two identity operators:

Operator Description

is Returns True if both variables refer to the same object.
is not Returns True if both variables refer to different objects.

Program 8: To demonstrate the use of Identity operators.

# Assigning a list to variable a
a = [10, 20, 30]

# Assigning the same reference of a to variable b
b = a

# Creating a new list with the same values and assigning to variable c
c = [10, 20, 30]

# Using ‘is’ operator to check if a and b refer to the same object
print("a is b:", a is b)

# Using ‘is’ operator to check if a and c refer to the same object
print("a is c:", a is c)

# Using ‘is not’ operator to check if a and c refer to different objects
print("a is not c:", a is not c)

Output

a is b: True
a is c: False
a is not c: True
