Python Identity Operators
Python | Identity operators: Here, we are going to learn about the various identity operators in Python with their usages, syntaxes, and examples.
Submitted by IncludeHelp, on May 31, 2020
Identity operators are used to perform the comparison operation on the objects i.e. these operators check whether both operands refer to the same objects (with the same memory location) or not.
Following are the identity operators,
Operator |
Descriptions |
Example |
is |
It returns True if both operands refer to the same objects; False, otherwise. |
x is y |
is not |
It returns True if both operands do not refer to the same objects; False, otherwise. |
x is not y |
Syntax:
operand1 is operand2
operand1 is not operand2
Python 'is' operator example
# Python program to demonstrate the
# example of identity operators
x = [10, 20, 30]
y = [10, 20, 30]
z = x
# Comparing the values using == operator
print("x == y: ", x == y)
print("y == z: ", y == z)
print("z == x: ", z == x)
print()
# Comparing the objects
# whether they are referring
# the same objects or not
print("x is y: ", x is y)
print("y is z: ", y is z)
print("z is x: ", z is x)
print()
Output:
x == y: True
y == z: True
z == x: True
x is y: False
y is z: False
z is x: True
Python 'is not' operator example
# Python program to demonstrate the
# example of identity operators
x = [10, 20, 30]
y = [10, 20, 30]
z = x
# Comparing the values
# using != operator
print("x != y: ", x != y)
print("y != z: ", y != z)
print("z != x: ", z != x)
print()
# Comparing the objects
# whether they are referring
# the same objects or not
print("x is not y: ", x is not y)
print("y is not z: ", y is not z)
print("z is not x: ", z is not x)
print()
Output:
x != y: False
y != z: False
z != x: False
x is not y: True
y is not z: True
z is not x: False
