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

Examples

python

fruits = ["apple", "banana", "cherry"]

print("banana" in fruits)

python

fruits = ["apple", "banana", "cherry"]

print("pineapple" not in fruits)

The membership operators also work with strings:

text = "Hello World"

print("H" in text)
print("hello" in text)
