# Identity operators

Identity operators are used to check if two variables or two values are located at the same memory location.

Here is the list of identity operators in Python.

 Operator Meaning Example is True if two operands are identical (refer to the same object) x is True is not True if  two operands are not identical (do not refer to the same object) x is not True

Note: If two variables are equal, it does not imply that they are identical.

Example : Identity operators

value1 = 1

value2 = 2

string1 = 'Python'

string2 = 'Python'

list1 = [1,2,3]

list2 = [1,2,3]

print(value1 is value2)

# Output: False

print(string1 is string2)

# Output: True list2)

print(list1 is list2)

# Output: False

print(list1 is not list2)

# Output: True

Output

False

True

False

True

Here, value1 and value2, string1, and string2  have the same identity since they share the same location. The list1 and list2 are equal but not identical. To verify the same we can check their identity using id() function as shown below.

print(id(value1))

#Output: 1672071312

print(id(value2))

#Output: 1672071312

print(id(string1))

#Output:21102080

print(id(string2))

#Output: 21102080

print(id(list1))

#Output: 62238968

print(id(list2))

#Output: 62239248

​​​​​​​Output

1672071312

1672071312

21102080

21102080

62238968
