Introduction

The membership operator of python checks for the membership of the given value in given range. Python provides the two in-built membership operators:

Identity operator	Meaning
in	Returns True if the value is present in given sequence otherwise returns False.
not in	Returns True if the value is not present in given sequence otherwise returns False.

Example 1:

x = [10,9,8,7,6,5]

y = 5

if y in x:

print(“Present”)

else:

print(“Not present”)

Output:

Present

Example 2:

x = [10,9,8,7,6]

y = 5

if y not in x:

print(“Not Present”)

else:

print(“Present”)

Output:

Not Present
