Identity Operators and Membership Operator in Python

 Identity Operators and Membership Operator in Python

Identity Operators

Identity operators are used to compare the objects, not if they are equal, but if they are actually the same object, with the same memory location:

ये चेक करेगा की दोनों object या variables या value बराबर हैं या नहीं यदि हैं तो true return करेगा वरना False return करेगा।

Operator	Description	Example
is	Returns true if both variables are the same object	x is y
is not	Returns true if both variables are not the same object	x is not y

Example:-

X = 10

Y = 10

Print(x is y, x==y)

Output:                                True, True

X = 10

Y = 10

Print(x is not y, x==y)

Output:                                False, True

X = 5

Y = 10

Print(x is not y, x==y)

Output:                                True, False

Or

X = 5;

If(type(x) is int):

                Print(“Correct”);

Else:

                Print(“Incorrect”);

Output:                                Correct

Membership Operators

Membership operators are used to test if a sequence is presented in an object:

ये operators Data Type पर काम करते हैं जैसे List, Tuple, Dictionary etc. यदि list मे कोई वैल्यू या string मौजूद है या नहीं तो ये हमको True या False परिणाम रिटर्न करता है।

Operator	Description	Example
in	Returns True if a sequence with the specified value is present in the object	x in y
not in	Returns True if a sequence with the specified value is not present in the object	x not in y

Example:-

X = “Hello”

Print(‘h’ in x)

Output:                                False

X = “Hello”

Print(‘H’ in x)

Output:                                True

Or

X = 10;

List = [1,2,3,4,5];

If (x in list):

                Print(“Yes x is present in the list”);

Else:

                Print (“No x is not present in the list”);

Output:                                No x is not present in the list

X = 10;

List = [1,2,3,4,5,10];

If (x in list):

                Print(“Yes x is present in the list”);

Else:

                Print (“No x is not present in the list”);

Output:                                Yes x is present in the list
