Python in operator

Python in the operator is used to check if a value exists in a group of values (string, list, tuple, etc). The in operator returns True if an element is found. It returns False if not.

Python in operator

A simple example code check specified value is inside the sequence.

list1 = [1, 2, 3, 4, 5]
print(5 in list1)  # True

s = "A is A"
print("is" in s)  # True

tuple1 = (11, 22, 33, 44)
print(88 in tuple1)  # False

Output:

Let’s see the in operator in the if..else condition.

s = "Game of Thrones was the good show"
if "Thrones" in s:
    print('It exists')
else:
    print('Does not exist')

Output: It exists
