Types of Membership Operators

There are two types of membership operators in python language.

• in
• not in

i) in

The in operator checks whether an object is contained within another specified object (usually a list). If the list contains the object, it will return True.

Example 1:

object = [34, 23, 55]

print(34 in object)

Output:

True

Example 2:

language = ["python", "java", "react"]

print("python" in language)

Output:

True

ii) not in

The not in operator returns True if the specified value is not present in the object.

Example 1:

age = [45, 23, 89, 20]

print(33 not in age)

Output:

True

Example 2:

brand = ["hp", "dell", "apple"]

print("dell" not in brand)

Output:

False
