Identity Operator

The identity operator is used to verify or check if both the operands refer to same memory. that mean to compare the memory location of two objects memory identity operators are used.

If both objects refer to the same memory location it returns true other and if not, it returns false accordingly.

There are two types of identity operators in python programming

1.  in

2.  is not

Now let’s take an example

A=15

B=15

Then,

A is b, will return true

Because both a & b are refining the same memory address of value 15

Note – you can use id () function to confirm that both are referencing same memory address.

Now if you change the value of any variable of a or b then it will not be referencing the same integer object and the result will come Boolean false.

See this,

A=10

B= 15

Then a is b will return false because both variable a & b are not referencing to the same memory location.

Why Standard Library Module in Python 

In this tutorial, we have learnt about Identity Operators in python for cbse class 11 & 12 and its related concepts according to cbse syllabus and this topic is very important to start learning python programing language for beginners of class 11th and 12th.This tutorial is also useful for Central Board of secondary education (CBSE) student of class 11^{th and} 12^th  , who opted computer science (Code 083) as an optional subject.
